I like the push and pull of possessing enemies to gain HP vs killing enemies to gain possession points. There's something good in there. The combat feels a little bit rough and the way you die super abruptly doesn't feel good, but that's pretty darn understandable for a jam game.
I really like the art! The crater-thing you come out of is super eerie and the animation when you zip from one body do another is great. The music is very moody - makes it feel like we're on the verge of something horrible about to happen.
I played a few times, and eventually got to a point where I was walking around as an ax-man and there was basically nobody left. Maybe I can count that as a win? :P
