The resolution of the graphics, motion blur, color and so on (the graphic side) is cool. I also liked that you framed it under a context (the protagonist is in coma, dreaming) so it gave some meaning to randomness. What I missed was some way of knowing how much life I've got left (instead an audio, you could go for a UI number or a health bar; classics). I am not sure if the jump mechanic was intended to work that way, but along with the fisheye camera it invited me to play "to fly", so I think you could improve the experience by making very vertical and intricate maps, like a vertical maze to be explored. Although the fact that I cannot point upwards beyond 45 degrees (aprox) made me a bit anxious; why not to remove it and let the player look up completely? ;)
PS: I think there's is a bug by which I was being shot constantly by an enemy I couldn't see.
