A problem that would arise with two player would be multi-key functions. Most keyboards i have seen/used are retarded and screw up when you hit like 3 buttons at one time... Maybe one player could be a bit offset and offbeat so they dont have to hit the keys at the exact same time or something...

Another suggestion is to be able to turn off the animations in the background...While i was playing zelda level, the stupid screenies of zelda kept slowing my computer down, but on blank levels, it didnt. There should also be the option to turn off all sound just in case players are idiots.

I also think there should be an option to gow through a song slower and lower the bpm, weird as it sounds, so i can finally beat that damned faster pianist!

Edit for NekkoChan!: I also think there should be a way to pause the damn game! i cant recall how many times ive been playing and a retarded popup hits the screen so i lose.
