It's not a very closed beta if you're posting it on a public forum
Anyway, the art and music are pretty good. The game itself was a little too slow and repetitive for me though. And vague. What does screaming do? What's the motivation for the main character? What benefit does exploring a large space have when there is nothing to see but more platforms? What is the challenge?
Anyway, I kind of got... bored. I'm sorry. I realize it's supposed to be an art-game kind of game with a message and such, but maybe being a tiny little bit less vague about goals would help. And I know I'm probably missing the point to this but I think a game with a message can still be challenging and fun to play.
It looks really nice though, I wish you luck at IGF.
