Got to level 5 and just didn't want to spend 30 minutes beating the level. The levels are really hard, but only because of the controls. If the controls could be made easier to grasp, cause It's hard to use two different hands at the same time (I'm not a piano player xD).
The concept was cool and I think if the game was polished work/worked on more, it can be a really fun game, cause I had fun!
