Hello, I was wondering if there is any chance of you guys adding a multiplayer category. I know people have asked this in the past but I doesn't seem like you responded to them on any of them (I don't know If you guys are just really inactive or what ever) I think this would be a great category for people who want to speed run with their friends (like me) Hope you at least think about adding It :)
In both 380 star and 100%, using multiplayer is definitely allowed. For Any%, it isn't explicitly stated whether you can or not, but I don't see a reason to forbid it. Mario% is probably single-player only because only one player can be Mario at a time.
