Please, don't add something that was not meant to be added. It's nothing but clutter. It was meant to be a change, not an addition. A lot of those are duplicates.

My intentions are to change the blocks to the bottom right "middle" block style. It's the best of both worlds and looks smoother.

I acknowledge it needs a background. How about a volcanic mountain?

However, I had lost my motivation long ago when I made a huge edit to colouring the outlines, then forgot to save.
