Static, it's called singleplayer for a reason. But I get your idea, although I still think it's easier to send the replay file to the person you want to collab with.

I wish there were more movements possible and I know it's probably been suggested before, but the hands, as they are now in Toribash, are lacking in capabilities and so are the feet. The torso isn't that bad. I know it would take a bit of adapting to get used to it, but it wouldn't really be difficult, would it now?

PS: Also, how close has anyone gotten to "real life" physics? I remember The -50 gravity thing, but that didn't work out because of the tori itself.
