Love the concept! I don't think I've ever seen the idea of using your corpses to help you get through the game - really neat! I was a bit impatient and didn't read the game description and found the level with the vertical wall impossible... until I read the description and realized you could freeze your corpses and then things got a lot easier haha!
A little buggy at times, especially when jumping while touching a corpse on the side, but that should be an easy fix! (looking forward to future releases if there are any)
And the ambiance you set with your music is great! Really fits the dark vibe and felt super natural. Overall great job on this one!
