I made these for my godot puzzle game duoban - a sokoban style game - I also made these boxes for this game...

I created a stone only version and two grass covered versions, one is a dark and slightly desaturated grass needed for my game as contrast to the player, the other is greener.

Also included is a gimp file, which allows to change the color of the grass without changing the rest.

Compatible with godots gridmap too.
