First, click the green flag. Then, a bunch of dots will appear. There are 8 types of dots, but some of them will not appear on the first try. If the "free" slider is on 1, then 4 types of dots will be controllable, and the other 4 types will move around randomly. If "free" is 2, then the opposite will happen. The "way" slider is to change the direction of the controllable dots and the "speed" slider is to change the speed of the controllable dots. And please remember, this is not a game, it is a simulation.
