Thanks! Yeah that's pretty much it, when you are drawing them just make sure that all layers are the same size so it's easier for the programmer to navigate them. Also remember to make each layer seamless if you are creating parallax effect so it will loop beautifully, imo the easiest way to make a layer seamless is to duplicate it, flip it horizontally and to erase all but a little bit from the side, then merge it to the original layer. These might be obvious tips but maybe they'll help!
