Otherwise, just make the walls have more friction so that things don't slide around on it as much. Like, come on, is that stuff coated with soap or something?
I would like it if throwing the doll against the wall did less damage. I want to be able to do it more, it's satisfying. I'm not going to just increase the health of the doll, because then guns wouldn't do much damage. Please and thank you! :P
Blunt damage is physics-based. You can change your drag force in the settings, or simply throw slower.
