Ok, could be better
The game isn't bad, but there is room for improvement. The music is pretty good, but it is too difficult. The bars seems to have no meaning, because I got the little glowing thing past what I assumed was the finish line many times on level three, yet each time it still said I failed.
The amount lost per note versus the amount gained when I note is hit, is out of balance. I understand wanted to make the game hard, but you don't want it to be too frustrating.
This could be a really good game if there were varying levels of difficulty, and the overall balance of the game was adjusted a bit :)
