A ghost girl wakes to find her fox — her best friend — missing somewhere in the cosmos. What follows is a search that takes her through over 100 levels of Gravity Ghost's beautifully hand-painted universe, where planets pull, bounce, break, spin, repel, and splash around the player as they orbit their way through the sky. The game challenges not with enemies but with momentum and physics, rewarding the player who learns to ride gravity rather than fight it.
