Before you use it

Each generated game uses a fair amount of model time and paid image calls. Expect a starting point, not a finished game.

Why it's useful

You describe the game and it plans it, makes the art, writes the code, runs the engine, takes screenshots and fixes what looks or plays wrong, then hands you a normal project to carry on with. Good for getting a working prototype on screen quickly.

What it needs

Claude Code or Codex, Godot 4 (.NET), Node.js 20+, Python 3, Chrome and some command-line tools. Art needs your own Google Gemini or xAI key, and 3D models a Tripo key, which cost money past their free allowances. Tested on Linux and macOS, not Windows.
