Some ideas
Add the ability to cut the buddy.ie item: knife, Chainsaw. add bruises and cuts to the buddy. some more skins becasue i dont hate any of the current skins .maybe a video game character..or Harry potter.. lazers. maybe you could have in the objects category little minion people that run around and use various weapons on the buddy. and one more nukes. make the buddy get radiation sickness. thats all for now. this game RULES!!!!!
