The "blue elevator" its like jump up to the elevator, and then it just brings you up.. Elevator reacts with new add force after u exit side colliders, and then u "Enter and Jump" to elevator again. Wooden crate/box it's here for another reason (other place to go up and find something :D I can't spoiler much :D). I planned, "Robootech" (main character) donť have "double jump" at start (not this version). So u need use "Wooden crate" it before that.
