Moon Jump
A self-contained mobile physics toy. Hold to crouch and charge a jump, release to leap, then swipe between eight worlds where the identical charge replays under each world's real relative gravity — from a modest Earth hop to a Moon float to a pathetic Jupiter twitch to drifting off Phobos. An altitude tape measures each jump against landmarks, and a shareable Jump License card charts your best jumps per world.
