Relativity is a puzzle game in which you control a robot called Gravitron on its quest to return home. Gravitron is an invincible robot with the ability to shift gravity, but such power comes at a cost: it cannot move on its own and can only shift gravity when everything around it is at rest. Lost in space, Gravitron must use its gravity altering abilities to manipulate objects like asteroids and balloons in order to reach teleporters that may just lead it home.
