Find Unity Projects Via Vollna Effortlessly

We are seeking an experienced back-end developer to finalize ad mediation and confirm functionality and polish our music app, Audioval (iOS & Android).
The app is ~90% complete. Most core functionality — including AdMob unlocks (currently suspended), AppLovin rewarded ads, free listen, and the artist portal backend — already exists in the app.
Because the artist portal backend exists in the app and the artist site frontend is mostly complete, much of the work can be copied/reused, making this task primarily integration, verification, and minor fixes rather than building from scratch.
The main goal is to integrate AppLovin MAX, add Unity Ads via mediation, optimize rewarded ad flows, and confirm that all existing features function as expected. If you do well on this project, there’s potential for long-term work on future Audioval features


Responsibilities-
*AppLovin MAX SDK
*Integrate Unity Ads through AppLovin MAX mediation
*Ensure AdMob unlock system remains in place but does not serve ads until suspension is lifted
*Configure AppLovin rewarded ads (30 sec) for the Unlock button
*Ensure instant ad launch when Unlock button is pressed
*Test ad flows across iOS and Android devices
*Verify artist unlock revenue split and slippage is correct
*Verify free listen banner ads route 100% revenue to the platform
*Track free listen progress per user/song (user_id | song_id | listened_seconds)
*Mark song “listened” at 80% threshold
*Restore progress after exiting/refreshing
*Do not track progress for unlocked songs
*Update genre song count dynamically based on remaining locked songs
*Ensure recommendation algorithm returns correct results
*Fix issue where currently playing song disappears on home page refresh
*Connect artist portal frontend to backend
*Backend already exists in app
*Frontend for the artist site is mostly complete
*Ensure Upload button works for artists in artist site and is connected to admin panel
*Fetch/update current user profile in site
*Fetch/delete songs in site
*Display aggregated plays & earnings (basic) in site
*Confirm login/signup with Google and Apple social auth works
*Improve initial loading for artist cover and genre pics

Requirements-
-Experience with AppLovin MAX, Unity Ads, and AdMob
-Strong iOS and Android development skills
-Familiarity with rewarded ad callbacks and mediation waterfalls
-Comfortable working with existing codebases
-Able to test on devices
-Clear communication and ability to follow instructions

Deliverables
-AppLovin MAX fully integrated
-Unity Ads integrated via MAX mediation
-AdMob unlock system preserved but inactive until suspension lifts
-AppLovin rewarded ads trigger instantly on Unlock button
-All ad flows confirmed to work correctly
-Artist pay split verified and no slippage occurs
-Free listen, unlock, and artist portal flows verified, with minor fixes applied as needed
-Code reused/copied from existing app logic wherever possible

I’m putting together a small Unity scene that behaves like a classic Rube Goldberg domino run. Think falling dominoes that trigger rolling balls, one interaction after another, until the final flag drops. The reference piece I need to match for scope and feel is here: https://celinesproject.wordpress.com/amplify-2/

Core mechanics
• Domino-style chain reaction—no levers or inclined planes, just rolling balls knocking into subsequent elements in a continuous, satisfying flow.
• Classic look: wooden-tone dominoes, realistic physics, no fantasy or sci-fi flourishes.

What I’ll hand over to you
1. A concept sketch of the starting platform and end goal.
2. Prefab ideas for the domino and ball models if that speeds you up.

What I need back
• A clean Unity 2021+ project with all assets, scripts, physics settings, and materials organised in standard folders.
• A playable scene that starts with one click, runs the full sequence without manual intervention, and resets with the R key.
• Brief read-me explaining any custom scripts or inspector tweaks so I can tweak timing later on.

Acceptance
If the chain fires from start to finish, all physics behave consistently on repeat plays, and the package opens error-free on my side, I’ll sign it off right away.

Skills: Game Design, C# Programming, 3D Modelling, 3D Animation, Unity 3D, Physics, Game Development, Unity

I’m developing a 2D adventure game focused on storytelling, dialogs, and puzzle-solving.
The project already has multiple levels and core systems implemented, but I’m currently blocked by several technical issues and bugs that prevent further progress.

I’m looking for an experienced Unity developer who can quickly understand an existing codebase and help stabilize the project.

Known issues:

Dialog system issues (dialogs break or don’t trigger correctly)
Items are saved but not displayed in the main menu
Player animations play incorrectly (stuttering, wrong states)
Some interactable objects stop working after level restart

Requirements:

Strong experience with Unity (2D)
Good knowledge of C#, ScriptableObjects, JSON-based save systems
Debugging and refactoring experience
Ability to work independently and suggest clean solutions
Clear communication with short explanations of fixes

Goal:

Fix critical bugs, stabilize core systems, and unblock further development.
Please include a rough time estimate for fixing the issues.

Simple animation in Unity that will simukate a lottey draw. Application receives results from TCPIP socket and then renders the draw in realtime

Hi,

I have a 3D level that I need a level designer for.
I’ve purchased 10+ different asset packs with various environments, so the work will be done using the assets that already exist in the game.

I’m looking for someone who can build, rework, and refine the level, with a good eye for detail, so the map feels fun and engaging. The level has a castle in the center, and the idea is that each corner/edge of the map should contain different interesting areas—such as a rocky environment or other themed zones. You’ll have fairly free hands to create what you think will be exciting.

One important restriction: I don’t want tall, dense trees that block the view of the sky. The sky must remain visible.

I can offer $100 for the complete job and expect a finished, polished level. If everything works well, there is a strong possibility of more work and future orders.

I’d also like to hear your ideas and suggestions on what you would build or improve after looking at the images. I’m sending this to several designers and will choose the one with the best ideas and proposals for the $100 budget.

Thank you.

• How would you do the job, what ideas comes to your mind.

2D Pixel-Art Speedrun Platformer - Seeking Collaboration for Vertical Slice

Hello,

My game is called Kunoichi: Perfect Run. It's a high-octane, competitive speedrunner designed for mobile, inspired by the creativity of Super Mario Maker and the frame-perfect execution of Neon White.

The Vision: Look, Feel, and Goal

The Look: High-fidelity, custom 16-bit pixel art (like Katana ZERO or The Messenger). The visuals should be clean, sharp, and easy to read at high speed.

The Feel: The controls must be incredibly tight, responsive, and "juicy." We are aiming for an insane Skill Ceiling. Haptic feedback and visual cues (VFX, screen shake) must perfectly reinforce the Frame-Perfect Landing mechanic. The player should feel powerful and in absolute control of their momentum.

The Goal: To create a viral competitive community where the player's run is instantly validated by an automated YouTube replay upload feature when they break a world record.

Immediate Scope: The Vertical Slice

I need to hire you to develop a fully functional Vertical Slice (a single polished level) that proves the core gameplay loop:

Core Physics: Auto-running Kunoichi with responsive Charge Jump and Frame-Perfect Speed Boost on landing.

Building Phase: UI to pan, zoom, and strategically place the first building element (the Bamboo Spring).

Scoring: Functional timer, Scroll collection logic, and a mock-up High Score display.

This initial phase is crucial to ensure the physics are flawless before moving to full development.

Screening Questions
To ensure we are aligned on the technical demands:

The core challenge is the frame-perfect landing. How would you ensure this mechanic feels tight and consistent across different mobile screen refresh rates?

How would you approach designing the touch/drag input for mobile UI to allow for precise placement and rotation of objects during the Building Phase?

Please let me know your estimated quote and timeline for completing this initial Vertical Slice (Phase 1 and 2). I have detailed GDO documents ready to share.

Thank you for your time.

We have a all ready made Unity game, however it needs some adjustments:

- Steam Leaderboard (Capability to see steam friends highlighted)
- Certain Key bind within the game Needs Adjustment
- Small easy game mode needs added, (Basically a timer, so the game ends after 7 minutes of uninterrupted gameplay)
- Some UI Replacements

I’m building a basic 3D fighting game in Unity and want a playable prototype that demonstrates core mechanics end-to-end. Unity (URP or Built-in) and C# will be the backbone, with placeholder assets perfectly fine at this stage—the priority is functional gameplay.

The prototype should open to a start menu, load a single arena, and drop two characters in with health bars and round logic. One character will be player-controlled (keyboard / gamepad) and the other may be either a second local player or a simple AI with a short state machine (idle, approach, attack, block). Camera work, hit detection, damage calculation, and basic combos are all part of the initial scope. Cleanly separated scripts and inspector-exposed variables are essential so I can tweak balance later.

Deliverables:
• Unity project folder ready to open in 2021.3 LTS or newer
• C# scripts fully commented and organised
• Placeholder animations / models wired up to prove mechanics
• Short markdown read-me explaining scene setup, input mappings, and next-step hooks

Once the prototype loop feels solid—movement, attacks, blocking, KO and restart—I’ll take it from there for art polish and network play, so keep the code extensible.

Skills: Mobile App Development, Game Design, C# Programming, Animation, Unity 3D, Game Development, Unity, AI Development

I'm looking for someone who knows UNITY and is good with UI/UX. I don't need anything too dramatic or crazy just a few tweaks that will propel the app into the market as something 'cool' - in particular the UI design for the inbox and smaller functions need some work.

I ask any job responders to please download the app www.pokexr.com and get back to me with particular details of what they would do.

I have a second post that I will not be responding to anymore because I need a UNITY DEVELOPER, not just a designer.

It's an already published Virtual Reality boxing game developed using Unity XR Interaction Toolkit for Meta Quest Devices, and I want to add some new features to it.

It currently offers side-view third-person gameplay. I would also like to add a first-person option. So the users can select exactly what experience they want. Around 50% of the work is already done.


Parts that are already complete:
1. Present an option to the user to select the desired gameplay style in Tutorial Scene and Settings Menu.
2. Stable first-person camera view with no animations with only gloves visible.
3. Gameplay UI is fixed and stays in front of the camera always.
4. Can move around freely with real body movement and can throw real punches without animations in first-person.

Requirements:
1. Present an option to the user to select the desired gameplay before the start of gameplay scene.
2. The opponent is not detecting player punches in first-person. Fix this. You'll have the opponent to take damage from the player's punches, with realistic collision. If the player hits the head area of the opponent, it'll be a head punch; if the player hits the body area of the opponent, it'll be a body punch.
3. Adjust the UI in tutorial scene so it always stays in front of the camera.
4. Joystick-based movement is somewhat working but not as intended in third person. Make sure player fighter moves freely and naturally in third person. Use left controller’s joystick for movement, right controller’s joystick for rotation.

I’m ready to turn a fresh adventure-game idea into a real Android title that can also generate steady income. The task covers the whole journey—coding the core mechanics, shaping an engaging story flow, integrating intuitive touch controls, and adding a simple but effective monetisation layer so the game starts earning as soon as it launches.

Unity, Godot, or any engine you trust for Android is fine with me as long as the end result runs smoothly on typical mid-range devices. Along the way, I’ll lean on your advice about scope and feature priorities so we ship in a reasonable timeframe without bloating the build.

Deliverables I need from you:
• A concise design document outlining gameplay loop, level structure, and basic art/style direction
• Playable prototype to confirm controls and core fun factor
• Release-ready APK plus all project source files
• Brief hand-off guide explaining build steps and monetisation settings

If you’ve shipped adventure games before—or any mobile titles that make money—your experience will be invaluable. Let’s build something players love and that pays for itself.

I want a fully-functional chess game for Android that lets two players face off either on the same device or online from different devices. Real-time online play is essential, so a reliable matchmaking or room-creation flow is needed alongside smooth local pass-and-play.

Players will sign in with their Google or Facebook accounts; social login should handle profile pictures and basic data securely. Once in a match—whether local or online—an in-game chat bar must sit just below the board so opponents can exchange short text messages without leaving the action.

Core goals
• Classic chess rules enforced, including stalemate, draw offers and resignations
• Local multiplayer and online multiplayer sharing a single code-base
• Social media authentication (Google / Facebook) only—no email or guest mode required
• Integrated in-game text chat tied to each match
• Clean, touch-friendly UI that scales from small phones to tablets
• Source code written for Android Studio, well-commented and handed over with build instructions
• One signed APK (or AAB) ready for Play Store upload plus a debug build for testing

I’ll consider solutions built with native Kotlin/Java or cross-platform stacks such as Unity or Flutter as long as they meet the above requirements and keep latency low—Firebase Realtime Database, WebSockets, or similar services are fine for the backend. After delivery I need a brief hand-off call or document outlining how to update assets, keys, and server settings so I can maintain the app myself.

Skills: Java, Mobile App Development, Android, Debugging, Game Development

I’m building a stylised water system in Unity URP and need a specialist who can take the shader all the way from core feature set to drop-in use across four existing levels: Kamand, Riyagari, South, and Peepal.

Here’s the technical baseline I already have in place and expect you to refine and finish:

• Custom URP shader with Gerstner waves, depth-based colouring, Fresnel reflections and refraction, all driven by a flowmap for believable downstream motion.
• Foam is the priority: I want dynamic foam that springs up only where characters, boats or props disturb the surface, fading naturally as motion settles. Shoreline or continuous foam isn’t required unless you need a subtle base layer to sell the effect.
• Ripples must combine real-time GPU propagation with mesh-bound constraints so they respect riverbanks and pools without leaking across geometry seams.
• Interaction effects such as splash particles, collision ripples and global speed controls should hook cleanly into the ripple and foam logic.
• The final shader has to run smoothly on Quest 3; smart LOD, keyword stripping or other URP-friendly optimisation techniques are welcome.

Deliverable
A prefab-ready shader (plus any helper scripts, custom render features and textures) integrated into the four scenes above and committed via Unity 2022.3 LTS. A short markdown guide that covers exposed parameters, how to bake or edit the flowmaps, and any performance toggles will wrap the job. If everything in each scene looks, reacts and performs as described, I’ll consider the task complete.

We’re looking for someone passionate about creating smooth and fun gameplay. Apply if you’re a good fit!

I’m preparing a new mobile title for release and need a sharp-eyed gamer who can stress the build and pinpoint any performance hiccups before it reaches players’ hands. Your focus will be strictly on performance testing: frame-rate consistency, loading times, memory usage, battery impact and other runtime metrics that influence smooth play on real devices.

You’ll install the current APK, play through all major game loops, and capture objective data (logs, FPS counters, temperature readings when relevant) alongside subjective notes about stutter, spikes or overheating. I expect a concise report that lists the devices used, the exact OS versions, the scenarios tested, the results you observed and any recommendations that could help the dev team optimise.

If you already use profiling tools like Android Studio Profiler, GameBench or similar, let me know—this will speed things up. The build is Unity-based, so familiarity with typical Unity bottlenecks is a plus, but not mandatory.

Deliverables:
• A structured performance worksheet (spreadsheet or PDF)
• Supporting screenshots or short clips that illustrate the issues found
• Clear reproduction steps for each problem

Turnaround is flexible this week, but the sooner I can iterate, the better. Looking forward to your insights and seeing the game run at its best.

I have an Android game built with Unity (you can try it here: https://play.google.com/store/apps/details?id=com.qualwiztech.royalking). Right now the game requires sign-in, but I want to open it up and polish the retention flow.

What I need:

• “Play as Guest” – Players should be able to jump straight into the game with full functionality, no account creation. Give each guest a unique, device-based ID so their scores feel permanent even if they never sign up.

• Global leaderboard entry – Every guest run must post to the existing global leaderboard exactly as a regular user would. If you prefer Google Play Games Services or another backend, that’s fine as long as the result is one seamless, cheat-proof board.

• Inactivity push notifications – If a player hasn’t opened the game for a set period (configurable in code), send a gentle push reminding them to come back. I already have a Firebase project; you’re welcome to tie into that, or suggest another reliable solution.

Acceptance criteria
1. Guest users can launch, complete matches and see their scores appear on the global leaderboard without manual login.
2. Returning to the game days later still recognises the same guest profile on that device.
3. A push notification fires after X hours of inactivity, is delivered to the device, and opens the game when tapped.

The project is self-contained in Unity 2021 LTS, version-controlled on Git. I’ll give you a branch to work on and test-Flight style builds for quick iteration. Let me know your turnaround time and any additional SDKs you expect to integrate so I can approve them upfront.

I’m building a level in Unreal Engine where groups of enemies must move convincingly through dense spaces, reacting to changing obstacles and one another with clean, reliable pathfinding. My current blueprints handle individual AI just fine, but once several enemies spawn at once, they begin colliding, hesitating at choke points, and generally breaking immersion.

Here’s what I need from you:

• Analyse my existing project (UE 5.4) and pinpoint why the crowd agents are tripping over each other.
• Configure or refactor the Navigation System—NavMesh, AIController, EQS (if useful), Crowd Manager settings, or your own C++ solution—so that dozens of agents can navigate hallways, stairs, and open arenas smoothly.
• Demonstrate avoidance, lane-keeping around corners, and re-pathing when a door suddenly closes. I’m happy to supply a small test map for this purpose.

I’ll provide the current project files, enemy BP/C++ classes, and a short video showing the problem spots. Please return a working build or plugin plus clear notes so I can tweak parameters later on. If you see opportunities for optimisation or smarter formation logic, feel free to suggest them—I’m open to improvements as long as navigation remains the primary focus.

I have an early-stage idea—internally I call it “bermain g”—that I’m eager to see running on screen. Because this is definitely a game-development task, I’m looking for someone who can translate my rough concept into a small, fully playable prototype.

Here’s what I already have:
• A short design blurb describing the core mechanic and win/lose conditions.
• Reference art and sound placeholders to guide the look and feel.

What I need from you:
• Build the basic gameplay loop exactly as described in my document.
• Integrate my placeholder assets so the prototype is visually coherent.
• Keep the code tidy and well commented so I can expand it later.
• Supply a simple README that explains setup, controls, and any external libraries you use.

Platform is flexible—choose the stack you’re quickest with (Unity, Unreal, Godot, or even a custom HTML5/JS approach) as long as the end result can run on a standard PC without additional licensing hassle.

Once the prototype launches cleanly, responds to input, and hits the victory/fail states I’ve outlined, the milestone will be complete. If that sounds straightforward to you, let’s start building!

Hello!


We are making a multiplayer (3-5 player) turn base board game and have a clicking bug with one of our mini-game [Unreal Engine 5.4.4]


It works with 1 hosting the game with then 2-4 clients (listen server)


Basically we have this mini-game where you have 8 steps to complete to win, steps 1/3/5/7 is with the keyboard and steps 2/4/6/8 is with the clicking


The problem is with the clicking steps, when we stand still with the cursor inside the circle, we have to spam click multiple time to get it right,


what we need is to simply be able to click once for each ball coming in the circle


It seems that when we don't stop moving with the cursor around the circle you can have no problem hitting all the balls coming in


The clicks are handled in a ProcessClick function but we don't think that's blueprint related


requirement : need someone who knows about unreal engine multiplayer listen server (through steam server)


here if you want to learn more about our game [https://store.steampowered.com/app/4017420/Space_Inflation/]


Here is a link with the project files so you can already check if you want by testing the mini-game itself to see what I'm talking about, you can trigger it with a button on the right side called "K&M mini-game"
[https://drive.google.com/file/d/1oGaadzy_BIFIddzG9KusnP1OTBfIzPoo/view]
(the file is 2.3 GB, upwork allow 1 GB only attach file)


Thank you very much taking the time reading this, let me know if you are interested

Highrise Studio is seeking a skilled LUA Game Developer with a strong proficiency in Unity. The ideal candidate will be responsible for creating engaging mini-games, including Blackjack and Flappy Bird clones, utilizing our existing assets. If you have a passion for game development and can produce high-quality work on time, we want to hear from you. Please include examples of previous work with your application.

• Have you taken a look at HighRise Creator Studio? If not please do so before applying.
• Are you able to be flexible and communicate via discord?
• How long have you been gaming?
• Describe your recent experience with similar projects
• Include a link to your GitHub profile and/or website

I have a word game app fully designed. I have all of the media files, (text files for word lists and full dictionary with all word tenses), WAV files (sound effects and soundtrack), and image files (PNG for all buttons and fields, jpg for all backgrounds) organized and in folders on Google drive. I have all of the various app screens assembled for reference. The UI is completely mapped out.

I have compiled an exhaustive proprietary dictionary for the game and have it as a text file. I don't need to source a dictionary from anywhere else for the game. It's all in-house. I also have the source words saved as text files as well.

I need your skills as a game developer. This is for Android and iOS.

I need API endpoints for Leaderboards, Account balance syncing, Head 2 Head queue, monthly Tournament and login/user account.

Head to Head is like a live multiplayer. The user will wait for the person they invited to accept and then the match will start. It can either be from a phone contact or from an online waiting queue. If the phone contacts don’t have word bank, they will have the option to download it once they click the link sent from the user. Once the match starts, the game isn't dependent upon the other user's actions. The clock will start running.

I would prefer for saved progress to work across accounts (server database) and on the device (PlayerPrefs / local JSON).

Users will have the option to be able to delete their balance, reset progress, and reactivate past source words. I have screens already set up for those features.

I would like for there to be an ad system (Unity Ads / AdMob, etc. to maximize revenue), and I would like for there also to be in-app purchases (to buy Hints, complete Theme pack, etc.). I would like for the paid version to include unlimited hints (Hint button) and the full Themes pack. I would also like the user to have the option to watch an ad for a hint. The free version will be limited to 5 hints per word. The free version of the app will come loaded with five of the themes.

I only expect milestone builds after the prototype is delivered. I'm thinking prototype, then full standalone version, then the full online version with backend / online features in place.

I have the GDD. I did all of the work myself. I have a trademark pending, LLC already set up, domain names secured.

Please contact me if this is something that you would be interested in and able to deliver.

I'm open to profit sharing as well.

We are seeking an experienced Multiplayer Game Backend Architect who specializes in designing real-time state synchronization, anti-cheat mechanisms, and matchmaking systems. The ideal candidate will have a strong background in building scalable and efficient game servers, ensuring a seamless gaming experience for players. You will work closely with our development team to implement robust solutions that enhance gameplay and maintain fairness. If you have a passion for gaming and a proven track record in backend architecture, we want to hear from you!

I’m building a complex, simulation-focused project in Unreal Engine and want every square metre of the world to be generated on-the-fly. I’ve laid the conceptual groundwork but now need an expert who can both jump in and build key systems and sit with me to explain the what, why, and how behind each choice so I can maintain and extend the work myself.

Scope of help I’m looking for
• Terrain generation – height-maps, noise functions, biomes, dynamic LOD
• Object placement – rule-based spawning of meshes, foliage, props, AI volumes
• Environment textures – material blending, runtime variations, landscape layers
• Full control over mesh properties – lighting, shape deformation, instancing, optimisation tips

The engagement is part hands-on development, part live consulting: short recorded calls or screen-shares where you walk me through how to navigate the Blueprints/C++, discuss best practices, and answer questions about the engine’s tools.

Acceptance
A small prototype level that demonstrates the systems above, plus clear commentary (in-code or doc) so I can replicate the workflow.

When you respond, focus on your Unreal Engine experience—especially procedural generation, World Partition, Houdini-Engine, or any custom tooling you’ve created. No lengthy proposals needed; proven experience is what I’ll be reviewing first.

We are creating a story-driven, point-and-click adventure game with rich environments, interactive puzzles, and branching narrative choices. The game focuses on delivering a compelling story with memorable characters and immersive world-building.

Responsibilities:

Implement core point-and-click mechanics (character movement, object interactions, inventory system)
Integrate branching dialogue and narrative choices
Work with artists and writers to bring storyboards and assets to life
Ensure smooth performance across PC and mobile platforms
Collaborate on UI/UX for menus, dialogue, and inventory systems

Requirements:

Strong experience with Unity and C#
Experience developing point-and-click or adventure games
Ability to implement interactive puzzles and branching narratives
Comfortable working with remote teams and asset pipelines
Attention to detail and a passion for storytelling in games

Nice to Have:

Experience with narrative tools like ink, fungus etc
Knowledge of optimization for multiple platforms
Previous work on narrative-driven or casual adventure games

I have a fully rigged game character waiting in Blender and I’m looking for a skilled animator who can breathe realistic life into it. The moves I need right now are a polished walk cycle, a run cycle that feels weighty, a natural jump, a smooth crouch, and a convincing attack. Everything should loop cleanly so I can drop the actions straight into my game engine without extra cleanup.

Realism is the guiding style—body mechanics should feel grounded, with believable weight shifts and follow-through. You’re welcome to start from motion-capture or key everything by hand, but the final curves must remain editable inside Blender.

Please work directly in the current Blender release, name each Action clearly, and keep the rig untouched so retargeting isn’t required later.

Deliverables
• Updated .blend file with each animation stored as a separate Action
• FBX (or glTF) exports of every move, ready for Unity/Unreal import
• Quick viewport playblasts/gifs for review and sign-off

I’ll give prompt feedback at each milestone to keep the process smooth and fast. If this sounds like a good fit, let’s get animating!
