Finish Game From Existing Code

I already have a sizeable repository of ready-made game scripts, assets, and demo scenes. The core mechanics compile, but the project still needs structured integration, bug fixing, and a clear path to a publishable build. Platform and genre are flexible at this point—we can keep it mobile, web, or desktop depending on what the current modules suit best, and I’m open to your professional advice.

Here’s what I need next:
• Audit the current codebase, remove redundancies, and squash obvious bugs.
• Hook up any missing systems—audio, save/load, input mapping, lightweight AI, and UI polish.
• Assemble a playable vertical slice that clearly demonstrates the core loop.
• Produce a clean, well-commented build that runs on at least one platform (Android, WebGL, or Windows).

Acceptance criteria
• No critical runtime errors.
• Build size stays under 200 MB.
• Stable 60 fps on a mid-range handset or integrated-graphics PC.
• Source compiles without warnings in the latest stable Unity or Godot (your choice; a port is fine if faster).

Please include links to past projects where you jumped into existing code and shipped a working game. A brief outline of how you’d evaluate my current assets will help me gauge fit. I’m ready to get started as soon as you can dive in.
