Just started the game and I like it. Lute playing reminds me of Loom, and it's great! Just one suggestion. May be in addition to easy and hard mode, you can make an expert mode, where making a mistake won't produce a warning and canceling of the tune until one is done playing. I think it makes it more interesting and fun for those who like musical instruments. Loom actually does exactly that (if you are wrong, in the end of the draft it just says that it doesn't sound like a draft).
