Okay, No. Piss on this game. I beat it, and aside from being a time waster, it brings nothing to the table but a fustercluck of a puzzle game that you pretty much have to brute force your way through.
By the way, to anyone stuck on the piano, once you get the piano hint that has the 2-8x, etc on it, the first digit is the key you have to hit. The second digit is how many times you hit it. (2-8x = press 2nd key eight times)
