You play for a shark in this game! In the beginning, your character is not strong enough as it is small. So you need to find as much for the protagonist to grow. When your little hero becomes bigger, the menu will also become more versatile. Soon, you can even attack divers and big predators. You will need to continue this pattern of behavior until you are the biggest and scariest resident of these waters. You must be so powerful that even other sharks shudder when you appear on the horizon.
