I don't suppose you could share the tilemap setup in Godot. I'm having trouble with understanding how to set up the more complicated things like cliffs and such.
Hi, of couse. Do you mean for the Autotile set up? Here is a screenshot of the auto tile setup I used for the screenshots. 
Using this method you will have to place the cliff face manually depending on the height of the cliff you want, but the cliff top edges are auto tiled.
If you want to auto tile the cliff edges too, in Godot, you can us CTRL in the tile map setup to merge the cliff face tiles vertically, and then they would be included in the auto tile (I think).
Hope this helps and you enjoy the pack. let me know if i misunderstood your question.
If you make a game or prototype, I would love to play it!
Thanks that worked out for me. Just hard to wrap my head around Godot's connecting tiles.
