This is a cool simulation but I'll admit it was hard for me to understand fully. It was like watching a nature documentary with no commentator, fascinating and peaceful but the innerworkings were lost to me. Maybe being fascinating and peaceful was the point and I missed it. I think this simulation has a lot of potential if you wanted to make some challenges to "gameify" it. Things like start the player with some creatures that are blue and small and use the evolution to make them orange and big.
