Blast off on a rip-roaring rocket into the furthest reaches of outer space on this roller-coaster ride in the dark.
Dip and careen into the inky blackness as a futuristic soundtrack echoes all around you. Fly past shooting stars and celestial satellites. Roar past streaking orbs of light, wayward comets and migrant meteors. Feel the pull of gravity as you’re drawn into a swirling wormhole!
