The idea to play with music scale sounds nice but i don't understand what i'm supposed to do either. The music played doesn't seem to match the music sheet i have in front of my eyes. It would have been also useful to show which character is playing the music at a given time, i think it's first the enemy that plays a melody and then my character that tries to mimic it and I have to pick the right note before the end, but if the sheet doesn't match with what i hear, it becomes very confusing :/ (Maybe i'm wrong, sorry it was difficult to follow, everything goes fast)
