This is a game for the Microbit where you are a pixel at the bottom moving left-and-right to dodge the falling pixels which drop faster and faster over time.

This Gist contains the various evolutions of the game which my son essentially wrote in the summer of 2024, but with help from me as he was learning to program. (I don't know Python either so it may not be idiomatic 🙂.)
