Each cat can perform 4 actions: walk, jump, short jump, and turn around. Every time they touch a yellow circle they must pick one of those actions. The actions "walk" and "short jump" will put them in the lava, "turn around" and "jump" will save them. Over time, each cat's AI will learn to savor actions that keep them out of the lava. If the cat touches the lava, it resets. If it survives (touches the wall), it learns to prefer that action a little more. See what happens! The timer is how long it's been since a cat fell into the pit. The IQ is the highest value of the timer so far.
