Something I've been working on for a while.
It's basically a circular lava chamber with a passage around the outside. The passage has a little ledge for running around, and the lava chamber has a health boost. Ammo and armor is placed in each quarter of the map.
So far, it's a little skimpy on details. The only detailed things are the gargoyles--please take a look at them, it took a long time to do them (and I still don't think they're quite right!).
As far as gameplay, it's rather simple--perhaps too simple. I tried to push away from the habit of making just one floor, but it only resulted in the ledge running around the outside passage. It should work better in insta than any other mode.
You might notice a somewhat rumbling sound in the background every so often, this is intended to be a constrained demon somewhere, but the sound didn't quite work right. (This is the result of that "delayed sound play" thread on the forum--thanks again to everyone who helped me!) It doesn't mesh with all the music too well, either, so feel free to disable it or set it to play only some music that fits.
The whispering around the pickups, however, work perfectly.
I welcome (and encourage) all comments; this is but my second "real" map and the only one suitable for actual play.
Oh, and this is my entry for the running contest... If I submitted anything else that qualifies for the competition, disregard it, please.
