From the README

A world where every organism that can see thinks with an evolved neural brain — and half of that mind is not its own.

Nothing is taught here and nothing is trained. The weights are shaped by selection alone.

every nearby mind also reads and writes

Weights stay private and inherited, so two creatures touching the same substrate interpret it through different minds. Thought becomes an environment that life both senses and shapes.

Watch long enough and regions of the map drift into different collective states — cultures, with borders. Press V to see them.
