Game is pretty fun! I liked the concept of possessing others to gain more power. I like as you get more power it just becomes a came walk, giving the player this idea that your crazy powerful now. Art is great.
Some nitpicks: Other than the fireballs at the end the mouse felt weird controlling the sprite flip. It didn't seem to make a different whether I was facing enemies or not while attacking, for a top down adding these directions is standard. So the player can visually see all four directions. I think I bugged the eye balls out near the end, it seemed if I got too close to enemies they would just bug out and not attack.
Enjoyed it. Good job!
