This level mock-up was made for homebrew 8-bit console game project, which was cancelled by some reasons. I'm actually more programmer than artist, and this picture was made to show project's artist how to draw tiled backgrounds (and also my skills).

16 colors, constructed from 315 8x8 tiles. Note that image is 3880 pixels wide, click to see whole image. Also note that it was made with limited number of tiles to fit into console video memory, because of this much of copy-paste was used and whole picture looks repetitive.
