This build is real-time 3D rendered in the browser. It is now evolving into a tiny fly life sim: multiple flies, heritable DNA traits, competition, courtship, resource chasing, and a stylized world that can evolve into a playable scene.
Buttons or keyboard: A add fly, Shift+A add 5 flies, P poop, W water, D dust, Space scare. Use the camera picker to jump between flies or free cam, or press 1-9 to follow a fly and 0 for free cam. Click a roster card to edit it and double-click to snap the camera to that fly. The DNA panel lets you randomize or manually tune behavior and body traits.
