I've named this map 'Cave', but 'Mine' would have been equally appropriate. Little bit of experimentation with an underground type map. No monster teleports, no keys and no doors.       I'm releasing it because I want to get feedback and I like spreading the Doom love, but I'm not particularly pleased with how it came out. There's something about it that I can't quite put my finger on that I didn't like. Anyway, maybe it's because I overplayed it testing the different section
