What they used: Developed by combining AI coding tools like Cursor and Claude. It was built by solo developer Pieter Levels (@levelsio).
What they did: He brought a browser-based 3D flight simulation game to life in a short time by having AI write the code. It later drew attention for being monetized through in-game advertising and more.
What it does: It showed that even without being a full-time game developer, you can publish a playable web game by leaving the implementation to AI. It dramatically speeds up the path from "build it, ship it, and watch the reaction."
