There are lots of glitches that force you out of a zone and start a chapter over. I'd recommend some sort of suicide button. Maybe it only applies to me, but i've had to start both chapter 3 and 4 over.
Absolutely beautiful. A masterpiece. Unlike many games, this one has a moral. A real journey. Whether you learn from the messages here or simply enjoy the gameplay, it still stands. There are always the few producers out there who put more effort into expressing a message than into the game itself. After all, i grieve over my mistakes more than i actually learn from them. Every time someone brings it up, you'd be ashamed. But you have to conquer it. Set your priorities straight and go farther than that. Be the dreamer.
Your song was too complicated for the third graders over here, that's why we play burn the rope... But either way, i appreciate the 5 minutes you put into making the game =D
