Yes! As an experiment, I've generated several "variants" of the tileset, with a few color combinations, and transparent/opaque background, imported them into LDtk and defined some rules, it worked really well!
This gif immediately sold me on this tileset, btw. So, so good!
Thank you very much!
Is it possible for these variant tilesets to be included in the .zip or be made available some how? ^ This looks amazing!
