This is a really gorgeous set, reminds me a lot of Zelda games. I started working on an RPG maker game that I plan to draw all the assets in, but I wanted something to start with so I wouldn't get bogged down in drawing stuff and never being happy with how it looked.
Seems you haven't quite worked out RPG Maker MZ support so I'll have to do a fair bit of 'reformatting' of things. Which is too bad, I hoped to be able to just buy it and go. But I know how to use Photoshop, so it's not the end of the world.
Still, it would have been really nice to be able to just drop these into RPG Maker and go instead of having to do a bunch of work :) (their auto tile system gives me a headache. It's not that complicated but it's still annoying.)
