I think it would have been better if the game controlled the order in which we got the items. I don't think the music should have a climax, since it seems very out of place when I'm just walking around. The girl fails to endear herself to me because she doesn't do anything and I don't know what her connection is to the boy. Also, why are the trees blue?
What I likes was that when an enemy or block fell into the sea they just kept sinking. It made me wonder about the game world and what made it they way it is.
Goodness, this game was annoying. A good concept, but why does there need to be constantly spawning past selves? I know that it's an art thing, but that doesn't keep me from dying for 4,286,046th time.
Definitely an Idea to explore on, but there doesn't seem to much of a sense of freedom. Maybe not make the points so obvious; just have certain surfaces that you can use to space-fold.
