Well....
It's a great acomplishment, lot of songs, etc.
But the fact that I can't lower the graphics hurts the game. The game begins to lag and then I miss all the notes. Also, I can just hit every note key and get the note, so there's no challenge. It'd also be helpful I could stay in the section of music I wanted instead of continually going to the menu to go to certain genres.
If these problems were fixed I would happily give it 5/5 and a 10, but because of them an 8 and 4/5 are what i'll give for now.
