"Hurl your star across spacetime, hitting targets and avoiding celestial hazards in your quest to earn a star that's big and bright enough to go supernova. As you play through the game’s 50-plus levels, you’ll meet new cosmic objects like small but dense neutron stars and massive blue supergiant stars."
