Damn. I had almost that exact thing typed into a TXT file and I was formatting it to post here. I was almost done, but then it came time for my haircut appointment, and I had to leave for an hour. During that hour, you posted.

On my way to the haircut appointmet, I toyed with the idea of making a little level editor in VB. But then it struck me: They must have a level editor of their own. In fact, it wouldn't surprise me if it was built in to the gameplay engine itself. I'll bet there's a line you put in the config file to activate the editing feature or something...
