Play as a marine creature and survive in the ocean. Choose your animal and east as much as you can, but remember it won’t be easy as this ocean is full of predators. Fight against other players in the ocean trying to eat your food, hide from them and score big. Evolve into bigger animal and increase your chances of survival.
As you eat food you will get energy (check XP bar at the bottom of the screen) it will change your creature with different traits. Run away if you find something bigger than you inside the ocean because it can eat you. Relax! This rule doesn’t apply to the players who choose the same species.
