Very fun game, playing it I noticed some good and bad parts about it.
The good parts:
1. The idea is exciting.
2. The levels are easy and well made.
3. The sound is good.
4. The general aspect of the game is extraordinarily well done.
The bad parts:
1. The sound becomes quite repetitive at some point, but it's still better than I've seen in some cases (when in some games there was a 3-5 second song sequence that kept repeating itself endlessly).
But good game. I liked it very much!
