Created for Crossfire RPG in May 2021 to replace some old graphics.

They are in an oblique projection, loosely following this hint:
"X and Y in graphics should correspond to X and Y in the object. Z in the object is represented with 2 Y/X."

earthwall-earth is the "canonical" set. earthwall-rock is a bit rougher on the top. The rest are merely palette swaps of earthwall-earth. (Is that allowed or necessary?)

Each zip file contains a spritesheet and 32x32 pieces of the sheet.

The spritesheet has a sub-blob formation at the top, which is the basis for the 16 tiles below it. If you want a full "blob" tileset, then assemble it yourself.

The names of each of the tiles on the spritesheet are as follows:

NUL NUL NUL NUL NUL NUL NUL NUL
NUL NUL NUL NUL NUL NUL NUL NUL
edge-4 edge-6 edge-E edge-C corner-2 corner-6 corner-7 corner-C
edge-5 edge-7 edge-F edge-D corner-5 corner-B corner-F corner-E
edge-1 edge-3 edge-B edge-9 corner-8 corner-3 corner-D corner-9
edge-0 edge-2 edge-A edge-8 corner-0 corner-1 corner-A corner-4
sink-0 sink-1 sink-2 sink-3 sink-4 crumble-0 crumble-1 crumble-2
crumble-v-0 crumble-v-1 crumble-v-2 crumble-v-3 crumble-v-4 crumble-v-5 crumble-v-6 crumble-v-7
crumble-h-0 crumble-h-1 crumble-h-2 crumble-h-3 crumble-h-4 crumble-h-5 crumble-h-6 crumble-h-7
port-v port-h NUL NUL NUL NUL NUL NUL"

Beware that the 32x32 images are RGBA, whereas everything else (previews, spritesheets) are indexed, which some software might not support adequately.
