Suggestion: ADD RUN TO THE LEFT (AND RUN EITHER WAY) --- I would like to suggest changing the name of the "RUNNING" exercise to "RUN TO THE RIGHT", and then adding in a "RUN TO THE LEFT" which would score fitness based on how far to the left a creature managed to get and "RUN EITHER WAY" which would score fitness based on maximum absolute distance from the starting point. I think this would be great for illustrating that it is the evolving neural network which ultimately achieves the specified task and not the specifics of the body design (although the body does have to at least have the potential).
