A downloadable game
You are a blackhole on a mission: consume the space colonies that aliens have been trying to develop. As you consume things such as asteroids and planets, you gain mass from them. Don't consume too much or you'll enter a state of critical mass and become uncontrollable and that leads to game over!
WASD to turn around
Spacebar to accelerate forward
Left Shift to slowdown/stop
Tab to eject mass. (Ejecting mass costs a colony. If you have no colonies consumed, you can't eject mass.)
