The player descends into the Pacific Ocean, navigating through coral reefs and shipwrecks. The goal is to collect as many sea creatures as possible within a set time limit. The core mechanic involves swimming through the underwater environment, using a limited amount of oxygen.
The player must carefully manage their oxygen supply while searching for fish, shells, and other sea creatures. Each species has a different point value, and the player's score increases with each successful collection. The game does not require any downloads or registration, and it can be played directly in the browser.
As the time runs out, the player's goal is to collect as many points as possible. The game ends with a final score, and the player can compare their results with other players.
