I Can't figure out what the difference is... probably because i'm dumb but xD What is the difference between Any% And True Any%? if anyone could explain that'd be great ;P

nothing anymore (at least that I know of) after the 1.2.0 update because the any% leaderboards take runs from any version of the game now (1.0.0, 1.1.0, 1.2.0)

True Any% allows Amiibo, 2P, and Assist Mode

Wait, True Any% has something to do with Bruncheon, right?

No, that's Star%. True Any% still means finishing Moon, and that's currently not possible via Bruncheon

OK.
