Awesome game, this feels so polished. But I have to agree with other criticism that the game was a bit too hard.
My biggest problem was understanding the timing of the collision with the top of the 3D pieces when the game was on the levels that were distorted. That made me stop playing in what I believe was one of the last levels, the distorted one with the 2nd ghost. Maybe you could have made it so the collision area of the pieces was a bit smaller in the distorted levels or something.
