Very entertaining game x'D. i'm glad reading some comments so i know what i have to do, and once you know it its all fun. The hardest part for me is to drill the hole since my mouse sensitivity is kinda suck haha, but i find a clever way to do it, i drill vertically, so even the note isn't suppposed to be pressed, i drill it anyway, and its fine on the game.
And that comes the other difficulty of your game, which is the note back ground that falling down, make me must really see what notes come from flute, maybe you guys plan this for the background, dang, can't beat my 8 point TvT, i always forget the last note haha.
I really like how you interpreted the theme :),
really cool game and fun music, rated <3
