I, too, just played it. It wasn't bad, but if I were the developer, I'd make one alteration: I actually got anxious as I started to leave the graveyard, what with all the creepy clouds and crows and sirens and everything, but I knew I was safe because I was playing the trial version. Imagine if, all confident in my invincibility, and the meat of the game (that is, the song) ostensibly over, I were to suddenly and unexpectedly keel over. I know I don't speak for most of you guys, but that would have won my vote.
Not that we're voting. Art is subjective, guys.
