Nice entry! A solid take on the theme! I liked finding all the different ways to kill the possessed souls. My favorite was the car lol. The animation popping in and out for the ghost is really solid. I wish he had a move animation, tho. The music and sound are great, and the game feels really nice to play.
For improvements, I would just suggest more variety in the hazards and maybe another level where the humans run from you or something. Some backstory on the ghost could be cool too!
Great work! Keep it up!
