I finally found the bug that I introduced, and removed it. Monsters are trying to hunt down and kill the player again.
I still need to add visible monster corpses though, and I need to add monster eating behaviors, like being full making them less likely to attack, and eating distracting them from trying to follow the player. (Not to mention more advanced stuff like gobbos hauling kills back to camp.)
Right now I'm messing with the architecture code to try and make the cavern levels follow my general plan: the catacombs, the cave river, the cavern forests, the underground meadows, and the lakes of the deeps. I'm trying to decipher how the existing code leverages the blueprint objects to generate interesting level pieces.
After messing with it a bit though, my biggest concern is that, in the state its in right now, it just isn't much fun. I'm hoping that as I continue to add my own flair to it, and increase the amount of interaction between items and the environment, the fun will start to emerge; but I don't feel that is a certainty.
There's really way too much to do in the final day tomorrow. It is likely that I'm going to fail, but I'm glad that I've given it a shot.
