Ok, so after FAR TOO MUCH TIME fiddling with Physics, the monster movement is now less bad. They at least now no longer oscillate themselves off to infinity. Not that happy with it, but it'll have to do for now as I have a zillion other things to do if I'm going to get all the mechanics in there today. Still cautiously optimistic, though I've had too many things taking far too long so far.

Next up: - Lighting (not just visuals, but a vital part of the (intended) gameplay) - Simple Minds (Best of) - Find something to drink that isn't coffee and isn't alcohol (yet).
