A very well-done game in many aspects. Good tone, interesting puzzles, and fluid controls and physics. The reason I am not scoring this higher is mostly due to how short and simple this game is for its genre. The game took me less than five minutes to finish. Your story premise is excellent and the storytelling is great, but because of the game's length, you don't expand on it very much at all. The puzzles are great but there's really no learning curve because of the length of the game. You are greatly talented and thus I would love to see more developed games come from you. This almost feels like a WIP.
P.S. there's a couple of bugs in the bottom room with the creature. Hitbox, screen transfer, and programming seem to be a bit buggy.
