You awful, awful son of a bitch. I have never wanted to actually punch a game developer before. You should be ashamed of yourself and I hope you and your children's children's children have nightmares of the horror you've recklessly inflicted upon the public.
Took me 556 deaths to get all 40 chests and finish. Many of them were due to a very old and crummy keyboard, but AT LEAST HALF of them were due to that level where you have to jump the blob through the spiked elevator shaft. My contacts are dry from not blinking, and I had to switch between AWSD and arrows probably 20 times to give my hands a break.
5/5, outstanding platformer.
