Got the air layer to look good while being able to see the ground layer slightly finally, it'll have to be smaller than the ground by a couple of tiles on the x and y but it at least looks appealing and one easily distinguish the difference between ground and air. I think the only thing remaining is figuring out a few shaders, finishing up 1 faction set of tiles properly, some more menus and certain global-level animations and that might be it for the graphic portion. I've seen it all, just listening to music I used to listen to 20 years ago (mp3 files with dates modified around that time).
