Very solid submission right here. The music is very eerie, but I am sure that is the intent behind it - so good job ^^. You had the time to implement the coyote time, which is always a big deal for platforming. I also really like the idea of the head of the character being detached from the body. It does make for more interesting death scenes with little work. Also not sure if intended, but I do really like how you can grab a ledge with your head.
The art style is quite nice, and I do enjoy the combat system, it's very enjoyable
