More recently, I’m a fan of shapez (shapez.io) for my recommended daily allowance of factory building gaming.
Going back further, I have a soft spot for Ri-li, a nice little game about toy trains with very charming music! It was this which set me on an adventure with the mod tracking scene. A surprising amount of open source games use them, it feels like open source music!
Reminded me also of Alex the Allegator 4, a very original 2D platformer
