Hi, can you add misc categories for each world (Pirate, Space, etc)? thanks

That's most likely gonna be a no, imo IW's aren't really a good fit for normal speedun leaderboards, they fit in more for Category Extension leaderboards, this game also isn't really split up into worlds but more traditional levels, if this game was like sms or whatever It would be main boards. you'll need to speak with a more knowledgeable mod about this, but i'm just giving out my thoughts.

I would say no. We already have each level individually as an IL, and doing them by world is just arbitrary. If you are not interested in running a main category like all levels, then just do IL runs.
