In the game, players control their diver to collect water samples from the ocean floor. The diver's movement is dictated by the player, who must carefully navigate through the water to collect the samples without running out of oxygen.
The main objective is to collect a set amount of water samples within a certain amount of time. The challenge lies in managing the diver's oxygen levels while avoiding hazards on the ocean floor. Water samples can be collected from various depths, each requiring a different level of care. The game runs in the browser, requiring no download or registration.
