I was working on an image for the background and had some trouble understanding how it's intended to work.
I found backgrounds split into three parts etc. What is the desired size?
Thanks.
Oh and here is what i am working on (wip). I grabbed the crystalcave/ground.png and put it on a dome. Now it's a crystaldome.
Still feel free to modify it. As usual CC BY 4.0. Enjoy.
