Our take
Ships twelve Agent Skills, a `um` CLI, a three-agent orchestrator team for long mods, and a shared knowledge base of field notes that agents can contribute back via pull request. Asset generation needs a fal API key (or local ComfyUI), plus Git, Python 3.10+ and ffmpeg; Blender is required for 3D to sprite renders. Also supports Codex, Gemini CLI, Copilot, Cursor and OpenCode, and the README notes the multi-agent setup uses several times the tokens of a single agent.
