Lovely art style for the game! Although it usually isn't much, a good starting screen and tutorial really set the atmosphere right and it looks great! I suggest lowering the interval at which the "Press Enter" text flickers though, it was very rapid.
People also already mentioned the distracting jump camera, but I would also lower the jump height. If the player can jump about 3 times its own height it'll feel more natural I think.
I also could not respawn when I hit the spikes.
Cool looking entry!
