You explore an alien machine, learn to operate it, create virtual organisms, and grow an artificial ecosystem inside it. You design species down to individual atoms and watch them fight for survival. You then send successful species to other players to leech energy from them and power your machine.

soul Interface is an evolution simulator / sandbox with functioning natural selection and space multiplayer. It provides multiple playstyles depending on which you prefer:
Involved - You get to design organisms with soft bodies made of individual atoms and brains made up of neurons and neural networks. You program or train their behaviors to outeat, outgrow or hunt into extinction competing lifeforms. Eventually, you get to send out your most invasive organsims and duel with other players, trying to overtake their ecosystems with your species…
Chill - You are tasked with growing and maintaining a virtual aquarium. You will create safe, warm currents to grow digital jellyfish; architect growbeds for virtual seaweed; or safe hunting grounds for baby sharks. Select species of plants and predators that coexist well together… and watch your digital ecosystem flourish!
All this wrapped in hand-programmed vector graphics, from an alternate reality 2000s. The game features full voiceacting and an atmospheric music score by our amazing composer, Geoffrey Guyer.
