This *is* a fun, challenging rhythm game. I beat all 12 main songs and a few of the others hidden up, but ultimately I think it is a little too punishing. When the beginning of a song seems tortuous because my fingers trip in the middle of the song despite practice, it simply gets frustrating. The game as-is SHOULD stay in the game, but as a higher difficulty setting. There are a couple easy solutions to make the game a better experience: either have checkpoints scattered throughout the songs, or have a system where you can miss a note or two and then on the second (or third) miss, the song fails. I don't mind a challenge, but when I complete a song and hate it because I've heard the beginning of it over a hundred times, the game is doing something wrong. Don't get me wrong, fun game, but be warned, it IS difficult simply to a weird game design decision.
