Oh yeah, body carrying I managed to put it in the jam game, I don't think many people noticed though :)
You can grab the hip and extremities of the body (feet, hands, head) and drag them around and throw the body as well. The strength of your throw and drag speed will be dependent on skill level.
I agree with the hub world and what me and my brother are designing will be close to that!
Speaking of, I just realized I haven't really talked about the setting and design of the game, I should focus my next development update on that. I think you're gonna like it.
