Desktop app · Electron · version 0.3.3

An AI that builds Roblox games with you. It asks the questions that matter, writes a plan in nine steps and doesn't build anything until you say go. Then it works directly in Roblox Studio through Roblox's official MCP, checks its own code and playtests the result.
Lucas and I build it together. Most of the code comes from AI coding agents. I plan and check every step.
What I did
- Product and design, from the first sketch to version 0.3.3 (12 Nov 2026)
- A shared brain on Cloudflare Workers and D1. A lesson only counts once it has been reviewed, and other developers can plug in their own AI over MCP
- A model router with a cost limit, plus our own benchmark, RR-Bench. On 15 hard Roblox tasks the same local model went from 51 to 65 points. It's a small test, so I read it as a signal, not as proof
- Game DNA: game mechanics that already work, saved as “genes” with safe limits (first version in 0.3.3)
- A texture engine that makes PBR textures for Blender models on its own
