An excellent asset pack, you really stuffed a bunch of great stuff in there!
The playable demo with randomize-able tiles is very much appreciated, a lot easier to see how it all fits together.
If I had any critique, it would be that some of the walkable tiles are so bright that they feel like solid objects. It might make sense to use white as an outline for some of the stone pathway tiles and keep them dark to better blend with the default ground.
Fantastic stuff!
