I recommend Turing complete! Its a puzzle game in which you learn how to make computers.
Its lightweight and written in Godot, plus there is a native Linux build. The gameplay is mostly figuring out how to implement something and you can undo any mistakes (assuming you find them). Might not be exactly what you had in mind, but I still recommend it!
:3 thanx. Hav headpats (if you wan ofc)
