This is hands down my favorite game that I've played so far. Everything about it is so well done. All the levels feel so clever and well thought out. I have no idea how you had time to make so many of them. The animations are fluid and just plain great. As a fellow mouth noiser, I commend you on you excellent exhalations. I literally laughed out loud at the end.
If I had to find one fault with it, it would be that the difficulty curve is all over the place. There are levels that I had to spend several minutes puzzling over that are immediately followed up by levels that I just blitzed through. On the one hand, it kinda gives you a break after racking your brain, but on the other, it makes the follow-up levels feel too easy.
