I think devs should cut snarbolax, twin, vana levels and jk levels into smaller battle rooms. Then each time a level is started, these battle rooms will be connected in a random order to form a complete floor (just like regular clockwork levels, or danger missions). That way each time players start a new run, they will feel like doing a new one with similiar theme rather than playing the whole thing from the beginning again. And maybe after this idea come true, the devs can make more new battle rooms to add them into missions to make it more various. I think making just a battle room cost less time than making a whole new floor right ? Just my tiny suggestion.
