I'm looking for an experienced Unity Developer to build a PC game prototype for Steam over approximately 3-4 weeks. The game is a 2D Action Roguelite / Survivors-like / Bullet Heaven, inspired by Brotato and Vampire Survivors, with an emphasis on polished gameplay systems and replayability rather than production-ready content. The project already has a detailed Game Design Document (GDD) and Scope of Work (SOW) covering the gameplay loop, player abilities, enemy AI, progression, UI, animations, audio, milestones, and deliverables. I'm looking for someone who can translate these designs into a polished, playable prototype using Unity. The prototype will include systems such as player movement, enemy spawning and AI, combat, experience and level progression, collectible pickups, transformation mechanics, temporary ally conversion, UI, save/load, and game flow. Placeholder art, animations, audio, and design documentation will be provided. Deliverables include: A fully playable PC prototype as defined in the SOW. Clean, modular, and well-structured Unity project and C# source code. Milestone-wise delivery of builds, Unity project files, and source code. Regular progress updates and milestone reviews. I'm looking for a solo Unity developer, preferably based in Mumbai, as occasional in-person discussions are preferred during development. While this is a paid contract project for the prototype, I'm also interested in building a long-term working relationship if the collaboration goes well. Please share your portfolio, relevant Unity projects (especially action roguelites or survivors-like games), your role in those projects, and your estimated timeline for completing the prototype. I'm happy to discuss the project further after reviewing your experience.

Hello, My name is Luis, and I am a game developer with more than five years of professional experience building gameplay systems, mechanics, and multiplayer and single-player projects. While Unreal Engine has been my main development environment, I also have experience working with Unity and C#. My strongest area is gameplay programming: translating design documents into functional, modular, and maintainable game systems. Your project is particularly interesting to me because it focuses on the quality of the core gameplay loop rather than the amount of production-ready content. Games such as Brotato and Vampire Survivors rely heavily on responsive controls, scalable enemy systems, progression, combat feedback, and well-balanced interactions between systems, which are exactly the areas I enjoy developing. I am comfortable working from an existing GDD and SOW, reviewing the technical requirements, identifying dependencies between systems, and organizing development around clear milestones. I also prioritize clean code, reusable components, proper project organization, and clear communication throughout development. Although I am based in Argentina rather than Mumbai, I work remotely with flexible availability and can maintain frequent communication through calls, written updates, gameplay videos, and milestone reviews. I am also interested in long-term collaborations and provide ongoing support for projects I have contributed to. Best regards, Luis

Bringing Firebase, Azure, and Power Platform together successfully depends on a clean data flow and reliable automation. For Action Roguelite Survivor, I can connect the required services, map and synchronize records, build secure functions or workflows, and include validation, monitoring, retries, and useful error logs from the beginning. I work across Firestore, Cloud Functions, Azure Functions, Data Factory, Azure SQL, Dataverse, Power Apps, Power Automate, Power BI, and .NET integrations. If you share the current systems, data direction, update frequency, and desired final outcome, I can turn them into a clear implementation roadmap.

As an experienced freelance web and app developer for over a decade, I believe I have the unique skill set, knowledge and adaptability to excel in building your Action Roguelite Survivor game prototype. Despite my extensive background being primarily focused on different platforms, like mobiles and web, I've also had substantial exposure to different gaming genres which I believe can be well applied in creating a unique blend for your particular project. Though Indie game development is new to me, the traits that define my style also epitomize what makes Indie games successful: creativity, resourcefulness, attention to detail and a focus on producing polished masterpieces at each stage. To ensure no compromises are made, I will closely follow the GDD and SOW you've provided while adding iterative improvements wherever they create an enhanced gameplay experience. I have tackled numerous projects that demand clean code structure, effective UI/UX design and intricate API integrations –- all pivotal elements for your game's success.

Hi, there The success of this prototype won't depend on how many features it has. It'll depend on whether someone wants to play "one more run." I'd build the core gameplay loop first and polish that before worrying about additional systems. That's usually what separates a fun prototype from one that just checks off features. I'd be happy to take a look at the GDD and SOW. hope your success Thanks

Hi, I am a Unity developer with 6+ years of experience building gameplay systems for PC and mobile games, including combat, enemy AI, progression, pickups, abilities, UI, save systems and complete game-flow management. For this prototype, I would first convert the GDD and SOW into modular development milestones, then implement the core gameplay loop, enemy spawning and combat, XP/level progression, transformations, ally conversion, UI, saving and overall run progression. I will provide regular playable builds and structured Unity project updates throughout development. My relevant work includes RPG combat and quest systems, third-person shooting and enemy AI, racing AI and progression systems, and multiple complete Unity prototypes. Estimated timeline is approximately four weeks, subject to reviewing the complete SOW. I am available remotely and can provide regular video calls and progress demonstrations despite not being based in Mumbai. Regards, Ahmad

Honestly the GDD + SOW already existing is what made me bid. Most projects here have none of that and scope just explodes mid-build. I'm new to Freelancer but not to shipping — i have built and deployed Mirror Reflection solo on Google Play Store, 250 levels, handled everything from procedural gen to AdMob to the full Android build. Link's in my profile. I play Brotato so I actually get what you're going for. That loop works because of stacking small decisions under pressure — I'll be thinking about that while building, not just crossing systems off your SOW. Three things I want to clarify before committing to a timeline: - Transformation mechanic — stat shift or does it change movement/attacks entirely? - Ally conversion — timer-based revert or kill-triggered? - Placeholder assets ready or should I pull from the Asset Store? Share the GDD whenever, I'll give you honest scope feedback same day. - Aayush

Hi, I'm a Unity Developer and Technical Artist with 3+ years teaching Unity/C# and a background in 3D art and multiplatform development. I've built survivor-like mechanics before – movement, enemy AI, wave spawning, progression, and UI integration. I see you already have a GDD and SOW – that's perfect. I'm experienced at following design docs and delivering clean, modular code that's easy to extend. A couple of quick questions: Do you prefer the new Input System or legacy? Any specific "feel" reference (Brotato smoothness, VS enemy density) you want me to prioritize? Timeline: first playable build in 5–7 days (core systems: movement, enemies, combat, XP). Then refine and polish based on your feedback. I work with regular milestone deliveries and clear communication. I'm new to Freelancer with no reviews yet – but I can share my portfolio and previous Unity projects so you can see the quality of my work. I'm offering a competitive rate because I'm building my profile here, not because I cut corners. If the prototype doesn't meet your expectations early on, we can stop without hard feelings – but I'm confident you'll be happy with the results. Happy to chat further. Let me know! Best, Arnau Merin
