The level is desert-themed, and I'm taking advantage of the sizable ledges and the doors and windows to create houses.
I tried to make some windows and arches. But, they didn't come out very well (I'm not very advanced with 16-bit graphics). I don't know about you, but the arches look like eagle beaks, or maybe the beaks on that scary door in SMB2.

Arch: background-99
