If the level meter gets stuck, replay the level after the one it says is the highest achieved, then continue to do so for every level after that. Wait for the level meter to change before going on to the next level. Also, for the last level the key is to click the right box holding up the ramp and the left box holding it up very quickly, so the ramp doesnt swing too much. Great Game.
This game is really fun, but if you hold down a note, it should only count for one miss. If i miss a chord i dont always notice and i almost instantly fail. + if you agree [:
