Excellent work
I swore I wouldn't review this game until I had opened up all those hidden, secret things, so here I am, a champion of this game, here to tell you that it is in fact one of the most kick ass games I've ever played. You did a really great job on this game (nice touch on the "Say Something" level). The only qualm I have with this game is getting the beat back once you've fucked up a little bit. It sucks, but like you said, it's not impossible. It does feel a little more difficult than it has to be, though. Just putting that out there.
Anyway, I'm off. This was excellent, and well worth the time you put into making it.
