A virtual aquarium meets a digital petri dish in two modes of the same experience. In the design mode, you build virtual lifeforms from the ground up — shaping bodies, laying out nervous cells, placing muscle fibers — and train their AI in a real-time 3D physics simulation. Organisms that successfully survive against species built by other players will spread to thousands of other players' worlds, earning you a share of what they consume. In the ecosystem mode, you take the role of a world-builder, creating ocean currents for digital jellyfish, growing virtual seaweed beds, establishing safe hunting grounds, and curating which plants and predators coexist well enough to build a stable, thriving digital environment.
