Fable 5.2 builds a nephew's dream game in one run, then scales to 18 characters

Fable 5.2 one-shotted my nephew's dream game

lexandstuff tested Claude Code with Fable 5.2, starting from a nephew's design sketches and existing game code. One run produced a playable 12-level side-scrolling action game. The model rewrote most of the code, generated about 175 images and 140 audio clips, and wrote a bot that played all twelve levels in a headless browser and checked screenshots.

Why it matters: The model wrote a bot that played all twelve levels in a headless browser and checked screenshots, using automated play and visual checks as basic tests for a generated game.
