In this game, players explore an underwater world to rescue a stranded submarine. Along the way, players must collect oxygen tanks, solve puzzles, and defeat water monsters.
At the beginning of the game, the player's submarine crashes in the Deep Sea. While the friendly sea serpent Jean Claude helps repair the submarine, the player must collect oxygen tanks by exploring the Deep Sea and completing activities. The oxygen chamber must reach its maximum level before the player can escape the Deep Sea.
As the player explores the Deep Sea, they must avoid pesky sea creatures. The player's health is represented by three hearts. Getting hurt by a sea creature costs the player one of their hearts. The player can jump on a sea creature to defeat it.

The player receives one oxygen tank for each level that they complete.
