Hi,
this game is lovely! The simplicity of the levels makes them hard, but because the physics are on point, I'm totally okay with that :) The sound of the ball I satisfying, just like the finding the correct combination of blocks. The game is very original, as I've not seen anything like it before, so good job on that. Where exactly is the looping part though?
Anyway, keep up the good work!
