Loved it, the game is super neat and pro, the animations feel good and are fun, I liked the graphic style as well, with the level that looks like it's moving!
The mechanic is clever and well used in the puzzles, nice job, you can be proud! It starts quick, has nice transitions and no loading times!
I'd just say that the fact that escape quits the game without question is very frustrating, it's a common key to trigger pause or try to cancel an action (like what I did at the last level to cancel the fact I picked up a block, it quit the game...)
