I like the concept of this game, and the level design is... to be honest, it's kind of mediocre. The walls that you phase through are a bit annoying, and I kinda wish there was some indication of them (although I'm sure better art would help). The levels are well-designed aside from that. Also, the corpses are placed a bit to the left of your body every time, which makes pressing buttons far more difficult than it should be. Good job though, it's a solid base for a puzzle platformer!
