I can make it change from counterclockwise to clockwise by scrolling down until it's off the top of the screen and then slowling scrolling it down. If I look at the feet of the shadow, it suddenly changes to clockwise...
It was difficult to change at first but I did it. I only saw clockwise. Look at the feet, then you could change it some how.
Yup it works that way. And if you look at the shadow it's even easier to change rotation.
