In a series of parallel universes where Earth is no longer able to sustain vegetation, you must pilot a spacecraft to the nearest habitable planet in humanitys final effort to preserve life itself by planting the last remaining seed. Each universe poses a route more challenging than the last, forcing you to use gravity to your advantage in order to orbit your way through swathes of planets, asteroids, moons and wormholes while using as little fuel as possible. Discover and unlock alternative spacecraft along your journey!
