The game space is a model of natural selection, if you are weak - you eat. So as not to be weak, you need to eat more. You start the game quite a small fish that has little chance to survive in this space, which is filled with predators. To survive, you need to find the fish smaller than you. Eating fish you magnified in size and will be able to eat larger fish. The more you absorb the production, the greater the chance of survival. On the left side of the screen there is an indicator that shows your current size and number of fish eaten.
