I love the sound effects, this is a great idea for a puzzle game. I haven’t seen anything like it before. It gets very hard very quickly though, I’d have loved some more easier levels for my tired brain. I don't have the mental energy to get past level 3.
Also at first I got stuck on level 1 because the UI to change the obstacles at the bottom was not obvious to me.
Overall a very well polished game and very satisfying as it gets harder and harder (but I hit the difficulty ‘wall’ too quickly and too hard)!
