The focus of this hack is entirely on level design - can you make every item, enemy, and coin placement meaningful? Difficulty is somewhere around a step up from Lost Levels, verging on kaizo-y with some of the tricks towards the end. Save-states shouldn't be necessary, but it gets pretty tough around world 5, so expect a few game-overs. Remember that you can hold A while pressing Start on the title screen after you game-over to retry from that world.
Features:
Very minor language warning at the end, but you may find it's well deserved - if you can make it there, that is. Good luck!
Version 1.1 update:
Lore for nerds: The Princess is tired of Mario simping on her, so she flees through a series of increasingly difficult worlds to escape him.
