3/5, needs more songs, needs to be a bit more responsive and maybe only use three notes e.g. left up right so that you can play faster and play the notes going up one after the other as you often do in guitar hero. But keep the speed decent, there is only about three people in the world who can play lines upon end at readless speed of all 4 arrow keys.
