Rewarding
The game rewards intelligence, which is good, but for the same reason it can't appeal to everyone, which isn't so good. The piano bit in particular was a little far fetched. I've been playing piano for a good 10 years and even now I can't tell what a note is just from listening to it. I could just be tone deaf though, no wonder I moved on to drums lol. It's pretty good as far as escape games go but it's just a little too difficult.
