I’m aware that I can use the CTRL + DOWN ARROW keys (on the PC) to move objects down (or back) within the same layer. I note however that you seem to be able to move an object through other layers also. Specifically when moving the overall shadow of the Knight. This can be seen right at the end on the “Drawing An In-Game Character – Front View” video.
What magic are you using to do this or is it merely a trick of the eye 🙂
