Here are a few pictures I've created for a title or "game over" screen. They're pretty simple, but maybe they'll be useful to someone out there. Click on images to see full versions.
Purple Night Variety:
Background for titles.
I couldn't decide if I liked Game Over or The End better, so both are included.
Blue Night Variety:
Title Background
The background image does not scroll, but you could also use it as a parallax image in small (17x13) maps.
