what are the hardest mario levels ever?

How about the Impossible Pack from NSMB2? Seems like a good place to start.



the most impossible thing is wanting to buy dlc for nsmb2 heh
 
champions road

fucking beep blocks, at least i can beat the perfect run
 
World 8 Crown from Super Mario Land

--- that course.
 
The Secret Courses from Super Mario Sunshine. The calm, happy music is ironic because of how you're completely enraged at the game for being cheap.

eh they aren't too bad, some of them take a couple of tries but overall not insanely hard
