I vibe coded a game with my daughter

My daughter and I vibe coded a little Cat Restaurant Game using VSCode, GitHub Copilot in its new-ish agent mode, and Claude Sonnet 4. The graphics were generated by ChatGPT; my daughter made the sounds and music using GarageBand.

You play a little girl that runs a sushi restaurant and has to feed the hungry cat customers before they get impatient:

The whole project took about three hours over two sessions. We never touched the code. Instead, the exercise was to take a vague game idea, make it concrete, break it into sub-parts that formed a coherent whole, and then describe each part in sufficient detail to get Copilot to generate the outcome we wanted. In other words, a great learning experience!

Because we never touched the code, it’s predictably wonky. For instance, it uses requestAnimationFrame() but fails to make use of the time delta in callbacks; I assume the game will run at different speeds on different machines. Another example: the GameState interface is a mishmash, confusing game state with input state among other things. But hey, the thing works!
