Addictive puzzle game Bobby is now free on Gameolith Linux Game Store.
In the game you play as Bobby, a bouncing bullet with a jetpack. There's nothing you'd like more than to rid the solar system of those menacing spheres. Fly around in outer space and knock balls into black holes in this arcade bounce-em-up. 75 levels and more than a dozen objects and obstacles await you.
