Build a game level from a design document
Real-world thread: the poster used Grok 4.5 to build level 2 of an existing Three.js game from a very detailed game design document, powered by their own game-dev harness as the setup around the model. The source only says the level was AI-assembled and then manually cleaned up and polished afterward by the poster. The result was a playable new level for the existing game, but the poster said it still lacked in several areas and they were polishing it.
