Read full description

Star systems are in chaos, twisted by an unknown force. As the planet’s last hope, you must master gravity to harvest vital X-matter. But be warned: the more you take, the more the universe unravels. Red is death, blue is life—the only rules between you and oblivion. Pure Arcade Action. No fluff, no menus—just you against the pull of a decaying universe. With intuitive one-touch controls and a haunting soundtrack that adapts to the cosmic collapse, the end of the world is here. And you’ll die for it.
