This is the exterior for the Academy in the Leaf Village
The shadows are a Tiled Background that I stretched over the entire area. When you run to a certain point in the layout, the background begins fading out/in depending on if you're in the darkzone or not
To achieve the lighting, I made some simple circle Sprites with the brush tool, put them on the same layer as the shadows, and set them to Destination Out (I think) so that they're essentially cutting holes through the shadows
