Mirrored World
[ I forgot to make sure More Slug Cats would play nice with this (it does not), for now it should probably be disabled ]
Mirrored World mirrors every room and region in the base game. Survivor and Monk work, but Hunter starts out inside a wall and dies instantly. Some rooms could not be mirrored properly (3 total), I may find a more graceful solution in a future update, but for now those 3 rooms remain unchanged. Only one of them is likely to be visited more than once in a playthrough (SL_AI for those of you who know the rooms by name), the other two are the very first and last rooms you’ll encounter; hopefully it isn’t too jarring!
