I'm loving the tilesets! They all seem to give off this vibe I can't quite put a name to, where they give off the impression of being "familiar, yet different"; The tilesets seem stylistically similar to something you'd see in an official Nintendo game, but they still look updated and enhanced enough to feel very fresh.
I feel similarly about the overworld, though the palette used there is a lot more "harsh" than anything else I've seen before. Not that it's a bad thing necessarily, just not something I can say I'm really used to.
