I don't really have a screenshot right now, but try this: 1) Acquire a Caraara Marble (Or however you spell it) 2) Place the gate down on solid, flat ground, preferably on a lower part of the map 3) Jump on a ladder (Longer ladders work better, and your y-position has to be higher than the y-position of the gate) 4) Activate the marble 5) Press up or down to climb on air. I think the game still recognizes that you're on the same ladder as before and lets you climb upwards. Sometimes you'll get stuck in the ground, which I believe has to do with the thickness of the ground tiles. Edit: Wrong version. Seems to be fixed in the newest one.
