The Plankton Simulator invites you into the hidden world of the ocean’s tiniest drifters. As a microscopic plankton, you navigate the vast, ever-changing currents, from sunlit surface waters to the cold, dark abyss. You must balance energy, avoid predators, and adapt to shifting temperatures, nutrients, and seasons. Each decision shapes your survival and growth in this delicate, unseen ecosystem where even the smallest creature plays a vital role in the ocean’s health.
