Could have been better...
I didn't mind it, but in my eyes it just doesn't stand up to the great GH style games such as super guitar hero manic deluxe etc. th quality was low and it was slightly glitchy. the music had no gradual build on difficulty. It seemed to be easy at first, but as soon as you play the second song it is beyond comprehension.
I would have liked to see more songs aswell, and maybe a longer bar, it seems as if the buttons are past you as soon as they come into view.
