This game looks very cool, and I love the change in music/overall vibe as you transition between real world and spirit world.
Maybe I'm just bad at this type of game, but it felt like the number of enemies ramped up way faster than I could handle, especially given the three-step process required to kill an enemy for real. All of my playthrus were basically: I kill the first few guys and then get completely overwhelmed by a zillion enemies. Maybe the game needs a slower ramp-up to full mayhem mode. It is also pretty overwhelming that for every single enemy you need to go through a whole process to kill it for real. I wonder if maybe it would make sense to have enemies/obstacles of some sort that DON'T need to be three-step killed so you can create the level of mayhem I think you're going for without it rapidly becoming totally unmanageable.
Overall though it's a neat idea with a very cool presentation and style. Grats on the jam submission!
