Neat visuals with a good concept!
It was a bit hard to understand at first, but I got the hang of it after a while! It was a bit difficult, perhaps because of the controls, but in another sense, the usage of the keyboard is what makes the concept unique! Maybe something that could work better is the top row of the keyboard and the middle/bottom row?
Regardless, still enjoyed it, also, congrats on your first Godot game! (,,,from someone with very little Godot experience haha)
