The default unity sky background behind the UI pages hurts my soul. The game is confusing at first, and it takes playing a few times to understand what's happening. I think every time I fall through the floor I'm being attacked by a shadow? I think? The giant 3D arrow that I'm guessing is a guide doesn't seem to work all the time, and it would be nice to see it more incorporated into the game. A nice particle effect creating a path on the floor, or a floating orb. I would also recommend incorporating the directions for the game into the game play rather than just having the player read them on a separate page. The small shadow character is cute, and I'm impressed by the amount of detail that was included in the character model considering it was probably done  in two days at the most.
