Quasarius

Quasarius is a Galaga clone with a pleasantly fast framerate. Just like in Galaga, gameplay can be broken down into three phases: In the first one, you fight a number of enemies ships. In Quasarius, their formation changes slightly each level and there is only a single type of enemy ship. In the second phase, you fight a boss, a larger enemy ship. There is just a single boss type in Quasarius. Lastly, you fly through a danger zone, evading asteroids and other space debris while trying to pick up bonus points.
