Use the joystick to move your character while swimming in the sea. Pirate ships will always chase you, firing cannons at you. Dodge the cannons fired by the pirate ships. Sharks will appear and chase your character. Press the attack button to attack nearby sharks. Defeating sharks earns you gold. Pick up items floating on the sea such as food to restore health, lifebuoys to help you move faster, seashells to throw at pirate ships to deal damage, and energy cans to restore health. After swimming for a while, your character will become exhausted and their movement speed will decrease after a few seconds. Use gold to buy food, lifebuoys, cannons to shoot back at pirate ships, shields to protect against sharks, and energy cans to restore health. Victory is achieved by destroying pirate ships; losing all your health means defeat. As the levels progress, pirate ships will fire more cannons, and there will be more sharks.
