Fantastic little platformer! I really love how polished the controls are, which is really the most important part to nail down this type of game. The levels were short enough that having to restart them over and over to pass to the next one really felt rewarding. (perhaps a bit skewed towards the later levels -- maybe make those a bit shorter?), it reminded me of super meat boy.
Graphics were really great, love the polish -- the animations, particle effects etc. were really spot on. The music was brilliant as well, and really added to the mood of the game. Theme-wise I like how you built your entire mechanic of spawning from the dead to solve the puzzles. There's a lot of potential there for a bigger game (maybe the person you rise from the dead can have different attributes and do various things to solve different types of puzzles)
Really great entry, awesome job!
