Featherfall Potion

Featherfall Potion slows the player's fall speed for 5 minutes and gives a bit of control of gravity to the player, allowing him to jump higher than normal. The player can hold the down (S by default) key to fall like normal in case of a rush, and the player can also hold the up key (W by default) to slow their fall even further or jump ridiculous heights.

Fall damage is also negated, even when falling normally.
