Fantastic!
Wow. This game is amazing!
Music- The music is very nice and not just stuff that anyone could think of with a bunch of the same power-chords over and over again. If i could play that well... I'd do a dance. Right now.
Story- The story was a good. It's kind of been used before, the whole "selling your soul to the devil" thing. But not in such a way as you have put it.
Graphics- Very visually pleasing. Also, my computer is pretty bad and i didn't have any trouble with lag at all.
Gameplay- Very cool. Sometimes it was hard to tell which dot to hit next... But then again, thats the whole thing that makes it difficult. =)
I would have never known that you had to translate. Great job. Keep on making great games!
