How?

I REALLY wish this was a category. I am trying to get it into Newer: Falling Leaf, by the way.

Does 'two submissions' mean all players in the run being different of some/all can be the same? Like me doing a run with a few others and some one else doing a run with featuring me.

Hi, is there any chance of Multiplayer% here? Why is it banned? I want to speedrun with 3 other players.
