Dirt with random lost-world debris? Such as random pieces of buildings (no text/letters), bricks of roadways, parts of statues, etc. But only a little debris, mostly just dirt.

Just make the blackness bricks like the destroyed bricks in the cornors of the first pic, and possibly a few debris like what Avenger said. And thanks for making the rain more visible. Looks great! :D

Wonderful.

Some kind of random symbols and shiz, with random ones glowing like.

I think some tanish orange colored background trees are needed to make the sky stick out less. Other than that, perfect.

Maybe like a dirt boarder that fades to black?

I think the black looks good as it is, it is a dark looking game after all.

if you make it dirt make sure it's really dark and has zimbols and glow simbolz too

You could make the darkness a grayscale & darker version of the neighboring backgrounds.

1. Make this game and make sure it's good
