This video should explain all but let me sum up. Its for 1.0 so it does not cover the latest features.
It creates glitchy ROM corruption like effects without changing any of the level data. Each time you go into a level, your character is shuffled but you keep the power-up you had last. Backgrounds,Blocks,NPCS are all randomized.
A water level might become a land level and vice versa or every block might become slippery.
To install just put the file into the folder of the episode.

in the lua file.API.load("corrupt");
And that's it load up the episode(ON A NEW SAVE SO YOU DON'T DAMAGE YOUR REAL ONE)
