I thought this was pretty fun! I really appreciated how all the characters were fully animated. It's a touch of detail that is quite nice.
I was a bit confused while playing about why health pickups seemed to be harming me, though. I would hug an enemy and I would sometimes get healed, but picking up health seemed to hurt me. Looking back on it, that may have been what you were going for. Still, making that a bit more clear would have been nice.
Overall, though, nice job!
