A multiplayer game built in four days without writing code

The full story

The author ran Claude Code in a loop for four days and it built a multiplayer strategy game on its own. They only touched about 5% of the code, at the end, for polish. First Claude interviewed them about the game design and turned that into about 248 structured tasks. A simple script then had Claude pick a task, implement it, test it, commit and repeat, throttled to three tasks then a 15-minute pause to save quota. The script is in the post.
