Pulse Jump is a tech that allows the player to jump a second time in the air. While activated, characters are able to release a pulse of energy beneath their feet. In order to activate pulse jump, the player must press Space while in midair.
The Pulse jump can be activated after walking off a ledge. It can be used right before landing to prevent fall damage.
As of right now, using Pulse Jump to prevent falling damage does not prevent 100% fall damage. In fact, it yields 1 point of damage after hitting the drop point of falling that will damage you.
