This is an experiment to see if I can create an effective AI, the size indicates the control over movement, and color indicates the speed. As the generation go on, watch the creatures change to the optimal speed and control.
I just whipped this up in like 15 minuets, so it isn't that good, only wanted to release it to get feedback to improve, so leave all that you can. P.S. use turbo mode (shift click green flag) for faster learning.
