Father builds son's typing game with Codex and deploys it to ChatGPT Sites

Meng Shao says he built a typing game for his son with Codex in about 20 minutes and deployed it to ChatGPT Sites, instead of buying a 128-yuan typing app his wife had found on the App Store.

The first version had 36 levels; his son played through 18 of them. Shao says he watched the play, had Codex fix problems as they appeared, and then added dozens more levels and an endless mode. He also added a live camera portrait feature for the player avatar. These details come from his post on X.
