Two-agent loop built a game in 2 days: screenshot critic agent bounced the sea 5 times
prasenx · x · 2026-10-07
Developer prasenx explains how his viral AI-generated game was made: one agent wrote the code, while a second agent that never saw the code kept reviewing screenshots and sending it back for fixes — the sea alone was rejected five times.
- The whole process took about two days, with the human only pointing out what looked wrong
- It wasn't smooth: on the first morning the sea rendered solid black, and the game opened with a character from his previous game
- He had used this generate-and-critique loop before, but never for two days straight
A concrete demonstration of a screenshot-feedback loop where an agent iterates on its own output, including its limits.
