Hungry Space
Hungry Space has mutant fish floating around randomly in outer space looking for food. They are all very, very hungry and you are going to die if you don't find fish smaller than you to eat. The more you eat, the bigger you get which means you get to choose from a wider variety of fish. However, if you bump into a fish bigger than you, you're eaten! While getting bigger can be good, it also means you're easier to hit. But you cannot move on until you are the biggest fish in this corner of the Milky Way so you might as well play Hungry Space and eat yourself huge!
