Summary
Players take on the role of Neptune as he dives into the ocean's depths to rescue his daughters, who are being held hostage by a sea snake. The game is divided into two parts. In the first part, players navigate Neptune through a series of underwater caves, battling jellyfish along the way. Players must also clear the path by shrinking overgrown weeds, which quickly regrow after a short time, requiring quick movement to pass through.
In the second part, players shoot crabs while dodging falling debris. After defeating a crab, players can carry it to a nearby structure where they'll find their daughters trapped in an aquarium, protected by the sea snake. To free the daughter, players must drop the crab onto the snake's tongue. Repeating this action multiple times will release the daughter, after which the game resets with increased difficulty.
