Thanks! This helped. I was confused because the other engine folders didn't seem to have all the tiles or images, so I went into RPG maker to get the rest. I'm trying it out in unity and it looks great
So after trying to use it for little while, I've notice one thing. I think the default "layout" of the tiles by default is a little strange. I'd recommend reorganizing them in a more seamless way (example below). I struggled with grass, as some of your examples show simple grass with little to no detail other than small grass blades. But your tilemap made it a tad confusing where the tiles were. structurally, it would help newcomers to organize them a bit.
It's a very good tileset nevertheless!!
