Wow, that looks promising! And awesome
I had an idea like that once. I can't remember the title, but there's this cool painting with staircases everywhere; on the floor, on the wall, on the ceiling. I think it would be cool if I could make a map like that and every staircase had it's own gravity, and people could run around upside down. It would make a great deathmatch map. But the gravity situation is complicated...
