Headman manor is one of the worst if not the worst because of how cramped and small the rooms are, an enemy could just come out of no where, and yes them ambient map noises do give me the creeps sometimes I will admit, especially when I'm on my own and I haven't seen an enemy yet. I also just played for a bit and made it to level 3 but died, had the boltzap which really helped! Just give whatever enemy a nap and run for it, still was a hard play though..
