Multiplayer runs should be allowed. They aren’t significantly game breaking and offer a fun experience for more players. Multiplayer is technically already allowed with the out of bounds glitch. Why not just include a multiplayer option?

You can play multiplayer in Any% if you want

Any% rules specify that only one player can control the game (ie. no multiplayer) but it's a suggestion we've gotten many times and will continue to discuss. I can say pretty confidently that some form of multiplayer will exist at some point, but we'd like to set up other stuff first. You're always free to do some multiplayer runs beforehand though!

@gasping-muffin is this to be continued. Me and my friends are planning a multiplayer route and we will probably execute pretty soon.

we're still planning on it yeah, not entirely sure what exactly the rules will be and when it'll happen but you can totally do a run and then submit once the leaderboard is made
