These are too cool! I am translating the tileset over to my RPG Maker VX Ace game, and these are a ton of fun to even just look at! Reminds me of something you'd play on an old-school Apple II or something and heck, like the original Wasteland.
I don't mean to be that girl but some of the tiles do have a very dark purple to edit out instead of a true black? But it's easy enough to find them and remove using the Magic Wand tool in Paint dot Net, or similar. Then I just Shift-painted all of those black. I found the purplish patch on the lower-left grass tiles, as I tend to do pixel work zoomed in.
Aside from that hiccup, these absolutely have my recommendation, especially for the great price. Bravo! <3
