The idea is nice and you play with it well in the first few levels! The minimalist look is nice, but everything is quite tiny and hard to look at.
The main thing I disliked was that every time you die, you have to click Play again and start over. The game isn't really a puzzle game like advertised. I am also not a fan of the level desing in the last two levels: I shouldn't win right after entering the room.
On the other hand, what I enjoyed were the sound effects and how the character bounces off things :). With a few changes, this game could be really great! It also reminded me of my similarly-named game "Splitt", haha :D.
