I have a playable concept sketched out on paper and now need it turned into a real, working game. The core idea, mechanics, art-style references and a rough flowchart are ready; what’s missing is an experienced developer who can translate all of that into code, iterate on feedback and guide the project from prototype to final build. You are free to recommend the engine that best suits the concept—Unity, Unreal, Godot or something else—so long as it supports mobile and desktop exports without sacrificing performance. I’ll be providing design direction, original art assets as they’re produced, and regular play-test notes. You’ll handle implementation, optimisation, version control and bug fixes, while also advising on technical constraints that could affect level design or monetisation. Deliverables • Technical design document outlining chosen engine, architecture and production timeline • Playable prototype demonstrating core loop and at least one complete level • Incremental builds at agreed milestones (alpha, beta, release candidate) • Final production build plus clean, well-commented project files I consider the job complete once the final build passes my test plan on both Android and Windows, loads within acceptable times and runs at 60 FPS on mid-range hardware. Let’s discuss the scope, milestones and any questions you have so we can lock in a schedule and get started.

Hi, I’ve reviewed your concept and understand you need a polished, cross-platform game built from your prototype and flowchart. I can take your sketches, mechanics, and art assets and implement them in Unity (or Unreal if more performance-heavy physics/graphics is needed) to create a playable prototype, iteratively refine levels, and optimise for Android and Windows to hit 60 FPS on mid-range hardware. The project will include a technical design doc detailing architecture, asset pipeline, and milestone schedule, followed by alpha, beta, and release candidate builds, culminating in a clean, well-commented final project.

Hi there! A great game starts with a strong prototype, but without the right engine, optimized code, and iteration workflow, even a solid concept can struggle to perform across platforms. Turning sketches and flowcharts into a playable, smooth-running game requires careful implementation, performance tuning, and milestone-driven builds. I am an experienced game developer with expertise in Unity and Godot for mobile and desktop, and I’ve delivered games from prototype to final build with clean, maintainable code. I handle core loop implementation, level setup, bug fixes, optimization for 60 FPS, version control, and advising on technical constraints to ensure gameplay and monetization ideas are feasible. I also provide incremental builds for alpha, beta, and release candidates, so feedback can be integrated quickly and efficiently. My approach will be to first produce a technical design document outlining the engine, architecture, and production timeline. Then, I’ll develop a playable prototype with at least one complete level, integrate your art assets, and deliver optimized builds for Android and Windows. Finally, I’ll provide the final production build with clean, commented project files, fully tested to meet performance standards. check our work https://www.freelancer.com/u/ayesha86664 Do you want me to recommend Unity or Godot based on your concept for the best cross-platform performance?
