In this underwater game, you play as a character who must survive by hunting enemies with a harpoon. These enemies move quickly and randomly, making the challenge difficult. At the beginning, you are almost out of oxygen. To survive, you must hunt the enemies and collect the plants they drop, as these plants give you the oxygen you need. Treasures hidden in the sand allow you to recharge your harpoon. The main objective is to last as long as possible before your character runs out. This is a survival game where speed and strategy are essential.
