The idea is crazily good! The difficulty, at least for me, it's too much though. It is hard to correlate what I see on the screen with what I need to press. I guess if you play more, you probably get it though. I reached the end in the easy mode. That's what I feel is the most appropriate level of notes to hit, at least to begin the game. I'll give a try to normal, but there is a lot of notes :D Nice game!
