As a guitarist I'm annoyed that I can't press the green and red keys at the same time and just get a red button recognised in game. Why can't I press buttons that are lower on the neck as well as the correct one? It's the very basis of ho/po and efficient playing...
Great game, the extra colours add a new level of difficulty. One thing though, you need to change is so that if you finish a line without using markers, the numbers ghost anyway.
