This is really good! A very well executed idea!
The ability to use your dead bodies to get places is a very interesting one, and you executed it well! The throwing was a bit difficult to pull off, since you aren't really told its trajectory.
The Art style was nice and simple, and everything was clear and easy to understand. The bobbing of the walk animation is really cute too.
The dying animation might've been a bit much haha.
Music would've helped with the atmosphere and really round out your game.
The platforming was a bit unpolished, as some jumps that should be easy were a lot harder to make. This made falling off at a later stage frustrating, since I had to attempt the clunky jumps again to reach the end of the stage. I would either make the jumps fairer or add checkpoints.
Other than that it's a really good game! Enjoyed playing it a lot!
