Super Mario Bros. Lost Levels Walkthrough Part 11: Painful Part

If you don't like a lot of deaths, don't watch this part or skim through it. The levels are getting extra hard for the home stretch. C-3 was far worse than C-4, that's for sure. The wind and springboard jumps put it's difficulty over the edge.

Level Time Stamps:

C-3... 0:00
C-4... 8:15

Enjoy!
