I had some spare time today so I created this visual tutorial which explains a bit about how layers work.
Feel free to look at it and tinker. Please leave me a comment if you want to see more, or less, of this kind of thing or have anything constructive to say.
I only speak English, but if anyone wants to translate it feel free.
The .json and the assets are in the .zip file.
Cheers and merry xmas
