Ive seen lots of people ask for this, but useally its a simple post just asking for it. So heres a Ruleset and a Video.

RULES: From a clean file, complete Story Mode

Timing starts on "Story Mode" select and ends on the beam shooting through Void Termina

Kirby cannot have a ability unless there is a player controlled friend alive

Amiibo is banned

Use of versions before 4.0.0 is banned as of the Version's release

Video Proof is required

Timing ends on this frame:

VIDEO:

Hey, that's what I wanted the ruleset to be, too!

Alright, the video is in.

If you have a friend willing to play this game with you, you should definitely try it.

Hopefully, Demolition gets to see this post.

Well really I would just like the mods to reconsider adding coop Any% to the leaderboard. Most forums that just say "Please add co op" with nothing else makes it less likely that Any% 2p (or 3p, or maybe even 4p, but no one would run that) would become a category

Not adding it

At an optimal level the run would be exactly the same except faster bosses
