This is Bing's entire engine IN ONE SPRITE. Just edit the "foreground" and "background" costumes. Additionally, you may want to have 3+ layers. 3 is easy: just add the absolute back layer to the "backgrounds" sprite of any particular project. For getting more than 3 layers, you will have to modify the code. I left some helpful notes inside of the code explaining how to do that :D CREDITS: @Bing8224 for all the assets and some code Me for reworking the program to fit in one sprite
