Open-source game tester from Ramen (Oct 30 2026) that plays your game in real time inside Unreal Engine 5, Unity 6 or Godot 4 on Windows and macOS. Give it a plain-English prompt like exploring a level, verifying that a tree shakes when hit, or beating a boss, and it reads your project's code, plays, and writes a bug report. It learns the game the more it plays, and also runs from Claude Code or Codex through its skills and MCP server.
