Reaction Game

A reaction-timing game written in C for a microcontroller, with physical buttons and lights. It is a real, finished game; it simply does not live in a browser.

Why you cannot play this one here

It runs on hardware, not in a browser. The repository is the honest record.

The code is public either way. Nothing about this game is hidden; it simply is not honest to put a play button on something this page cannot serve.
