I did another boss room type of thing inspired by Dark Souls and the feel of the Chalice dungeons from Bloodbourne. I think I went a bit too heavy handed with the foggy grimy atmosphere. Putting too much fog in things always feels like a bit of a crutch to me.
Ah well!
I try to stream at least once a week on http://twitch.tv/liminalbloke where I go through making this kind of stuff
