trepan,
actually, the corner artifacts exist in the original. Under 400% maginification you can just make them out.
as for seeing the maps. My plan was to post them, even if they are poor.

My end goal is to make a map that is less themed, just as complex, but more playable. The end result so far is a map that resembles something out of a random function generator more than a drawn entity. In battles against the BOTS, it does have some issues.
My next targets for this map is to add layers for the transporters, pyramids, and clean up the height/jump issues.
(.bat files: If I trusted windows a little more, I might go there. Right now, I am running with a series of shortcuts.)
.........you kids, get out of my tank...........
