Some preface: Gameboy/GB Studio thinks of its screen in 8x8px chunks.
GB studio has a background tile limit of 192 8x8px tiles (Roughly 112x112px total). The GB Screen has a total pixel area of 160x144px. I like using big splash images to mark transitions between ideas, but complicated illustrations that use every 8x8 are actually more pixels than the GB Has room for! So you have to make illustrations that repeat tiles here and there. Theoretically you can rotate/mirror tiles on the fly but I'm not sure how to ensure that's happening, BUT, I have found a cool way to check your work in Aseprite.
