First off, I loved the running animation.
I had a fun time running around blasting stuff; I got the voodoo staff early on and every other weapon I found didn't seem to be as good. I did get annoyed that once your inventory is full, you can't drop stuff, but you still "pick up" things off the ground (which seem to just get destroyed). So if I saw a cool thing on the ground, I had to craft something to waste some resources and make an empty slot so I could pick it up.
