since i rendered all of them i might as well put them up for anyone who can find any use for it

for instance :

i used it on the pointer where the player can click on the map to interact here , that's one thing, i use one for "viewport" which is a slight alpha-diff that signifies the "in-range" tiles where the player can't just look at but interact with (which is also the only place where objects are visible)
and then some ..

the tiles in the zip are all at least 256x256 (xept the viewport is 192x192 (3tiles wide/high) , the preview can be used as a 64x64 spritesheet (no borders, i think that's a waste of bytes personally)
