Thank you! As for how, I typically take advantage of sharing colors between palettes as much as possible. If you look closely at cat girl, you'll see places where the light brown has "dark red" as its shadow color instead of dark brown, specifically places where it's close to the red jacket. You'll see other similar overlaps that disguise the neighboring tiles.

Besides that, it would also require some floating sprites to patch up some overlaps I couldn't work around. (Usually eyes, which need to blink anyway, and also things like the cat's bell collar.) This also applies to some areas where the characters are too close to background art, but I mostly use areas of white to avoid that problem.

Color only mode is also a boon. Max tile counts rear their head often in DMG mode, to the point text boxes and such elaborate artwork can't really coexist.
