Fieldnotessim

A meadow in your browser. Rabbits eat the grass, foxes eat the rabbits, hawks eat both, and the numbers rise and crash in turn. Sometimes the meadow finds a balance, and sometimes it fails.

You choose how it starts: how many of each animal, a river, burrows, a pond. Then tune how every animal behaves, from how fast a rabbit runs to how far a hawk can see, and bring a wildfire or a drought to see who survives.

An ant farm simulator. You start with a queen and a few workers, and they dig the nest themselves: tunnels, food stores, nurseries, a graveyard.
