Yeah. I'm wishing i'd worked out what the hell the buildings were when i placed them in dev, cos i've ended up with "uh, well, a... crank room?" "a car, so a garage" and "lots of pipes".
I hear ya on the cliffs, particularly up the top where i've got way more space to work with and a 3d skybox mountain, some day, to add in. For now, however, i really can't justify any more time on this map. What you see in the shots is more or less what you'll get in the contest submission.
(So if there's anything obvious/easy-to-fix, let me know.)
