The game uses the theory of general relativity, that being how time flows slower for those in a
gravitational field, to provide the player with an arcade-style game about avoiding asteroids in space. In
play, the player controls a rocket spacecraft that goes into space, after taking off from Earth. As the
player escapes the gravitational field, by getting further away, time passes faster on the surface of Earth;
allowing the player to return to the surface and visit different civilisations. In these civilisations, the
player can upgrade their rocket with new modules that change how the game plays and let the player build a
rocket to survive the dangers of time travel.
