So apparently the all levels category has been changed to all castles, so this would make my guide useless, because you don't have to complete every level. FeelsBadMan

Oh, I never realized you had a guide, sorry for making it useless. :/

I changed it because All Levels is probably the most arbitrary category of any NSMB game, and it doesn't need to be there. All Castles, however, has been a staple of Mario games where you skip one or more castle in the normal Warpless. (examples: SMW, NSMBU/NSLU)

I know, just gotta make a new guide OpieOP
