I want to speedrun more inspiration island but we need new category’s pls make a category extensions.

If not, can I make unofficial category extensions?

Series mods don't add category extensions to maps or servers.

You should suggest some categories instead of asking for a whole category extensions page

Ok. Beating the game in creative, one lever, etc.

creative is already a category, one lever is too simple and boring, it's basically all levers just shorter
