This was my best attempt:
I had 96 c/gen( a 48 per batch), 70 gens and the brain was on default settings.
I first disabled "keep best creatures" and had a high mutation rate, then after i got a first jumping creature i enabled "keep best creatures" and set mutaion rate to a low level to get more like him. After i got a bunch of creatures like him i set mutation rate to a higher level to get again a creature that was significantly better than the rest. After this i repeated to lower and raise the mutaion level.
It also can "walk" as long as you want if you train it for some generations.
