Galaxy Invader

So ofcourse there is'nt an entire universe. But in this game, you have unlimited planets you can visit and these planets have their own randomly generated terrain.
In this game you're a "Space-Invader", and your main goal is to invade and conquer planets.
Once you've conquered atleast 10 planets, you've won!
So fly to whatever planet you want and kill some species from each planet.
