Any% would be good for this game and to see. Ive only really seen one glitch though and its where your hammer gets stuck between 2 things. But if any% becomes a thing i think sub2 would be possible.

It being more possible if a good glitch is found :/

"A good glitch might be found" isn't really a good reason to just make a new category. Categories are there to be played, not in case something happens in the future.

May I suggest a mouse acceleration % (I mean, it is the default way the game is played).

Maybe No skips%.Not using any skips

Hat%

I would say make a thread with a category you would like to see, explain the rules and show your own run of it. If people are genuinely interested in running the category they can reply with their own runs. Saying "I'd run it"/"This would be cool" isnt enough in my opinion. Actually do it. Just my thoughts on new categories
