Show HN: Checkpoint! Airport security sim game built with Claude Fable

[yaodub]

Fable just came out and I wanted to see what it was actually capable of.

The game: an airport security sim where manage passengers and keep them from getting angry. You place rope barriers, open lanes, build out a concourse mall. Pixel people route through whatever you designed. Standing still feels much longer than walking, so a long snaking line keeps people calm and a formless crowd gets angry and leaves. You're designing how the wait feels, not how long it takes.

Whole thing came together in one context window. I'm impressed.
