One other think @the_kov..... some possible rule suggestions.

-Maybe a rule about not using RentWizard or any other 3rd party rent or tower manipulation programs.

-Also a rule allowing or not allowing the lower left lobby double money trick. I know it is minor for the longer runs, but it might help with 2 star tower runs.

I definitely agree with 3rd party tools. for the lower left double money, for Any% i'd lean towards leaving it in. It's part of the game, I'll chat with some other mods from similar games and see how they feel about it.
