That was great
There was always a nagging in the back of my mind about this being boring, which I guess it sort of was, but it was a good time waster. I'd like it better if there was an option to turn off blood(instead of just one to add more), because somehow this just isn't the kind of thing I want to see blood in, especially on the default skin.
The physics engine was well built, I liked throwing in the gravity shifter with the magical orb and radio and using a mouse click explosion or missle ;)
All the weapons were well done; I especailly liked the fire effects and how the buddy could catch anything it touches on fire. Also, the way the radio shifts speakers depending on where it is caught me off gaurd as incredibly impressive as something to throw in. If you plan to make another, add more music to buy.
Overall, great job.
