Disorganization - Shuffles your inventory

Perplexity - Reverses your controls so forwards is backwards, sneak is jump, etc.

It also changes the way a few vanilla potions work:

Blindness - Now the fog comes closer per level (making you more blind), and it also affects mobs, so they won't attack you unless you are close to them.

Jump Boost - You can control how high you jump by holding down the space bar, so you can jump up one block instead of shooting into the air.
