I would absolutely love for a video game set in Elemental Air that takes advantage of the "subjective directional gravity" of the plane: "down" is the direction you believe it to be. This means that you can walk on walls and ceilings if you want. It also means that if you hold up an item and then let go of it, it just hovers in place: objects don't have minds and so don't think "down" is any direction. If you shoot an arrow or throw a ball it moves in the direction you threw/shot it until air resistance slows and eventually stops it; they don't arc.

It could be a puzzle/platformer and you play as a cute air genasi thief girl armed with a boomerang and a quarterstaff.
