Very cool! Can't wait for the full version!
I like how you can build your character, even though its obvious a lot of features arent done yet. So far no problems except the demo should have an actual ending instead of the loophole blob cave, and there seems to be a slowdown whenever you click something durring the game. I don't know if it is just my computer or the game but I have Windows XP, DSL, and the latest Flash Player so im pretty sure its the game, you might want to look into that.
P.S. Great music choice!
