damn near impossible for one simple reason... if you hit too many keys on your computer, that freezes your computer for a split second, during that split second you miss ten beats on max 300... impossible songs because the arrows are to close together and are too slow. move the random crap off the screen, decrease the size of the arrows and have them scroll from farther down. until stuff like that is fixed i can't rate this any higher, you get a four for good effort
