Here are some ideas I have for new categories:
-damageless
-no kicking (or any other move not being allowed)
-loose cannon only (also applies to all other fighting styles)

Damageless is pretty similar to the S-Rank category already since earning an S-Rank takes into account how much damage you take, and I don't think it'd work well to split up all the runs that have been done already with specific character categories, so I think we'll just stick with what we already have for now.
