Great
I Loooooooove Zelda OOT, and it was about time someone decided to make a rithm game themed on zelda (sorry if there is already one) but i really think it can improve a little --Dont get me wrong, the game and the idea are great--. ;), i suggest you try to make the keys more synchronized with the song.
Anyway just Keep on the good work!
P.S: by the way its Sheik, not Shake
