I noticed if you jump too high, the screen follows you, and when you are coming down if you touch the bottom of the screen you instantly die, even if there's a platform right below you. This can be pretty annoying.
There were also moments where I tried to jump as soon as I hit the ground and the jump wouldn't register, and I went flying off of the edge of the cliff.
Also making the player run infinitely would be nice instead of controlling him with the WASD keys.
Also was confused by the enemies. I thought they'd hurt me, but they seem to be helping me? Adding a little more clarity on what they do would be nice.
I like the derpy aesthetics though, it works. So nice work so far :)
