Breeders is a simulation of artificial life driven by physics and simple rules. It's a sandbox for exploring emergent behaviours, tinkering with ecosystems, and exploring the stress relieving effects of tossing around large numbers of bouncing boxes. :)
This week I created a few new critters, including a predatory amoeba that uses the Interactive Cloth features of Unity 3D. There's also the Katamari Bomb and some new source of the Catalyst objects that the Breeders need to survive.
