The sunlight that shines down upon this world is transformed into energy by green biots. But it's not a safe world for green biots. There are red predator biots that can feed on green biots. I wrote Primordial Life to capture the principles of evolution in an interesting and visual way. In comparison to Primordial Life 2.0, Primordial Arena 3.0 has improved physics, with rotation, momentum, and variable velocities.
Collisions are much more interesting, resulting in both rotational and transitional effects.
Biots now visually attack each other by removing each others lines. Biots now have propulsion lines to move around on their own. I've added a few other interesting features as well. Thanks for trying Primordial Life. To install Primordial Life, download Prim30.exe into a temporary directory and run it.
