Honestly couldn't get past the beginning. Tried saving first thing, tried giving the cigarette bud to the nicotine ghost dude, nothing helped much. Either way, I've barely managed to kill the hallway dude once, and I'm not sure why the amount of empty bottles (I made sure to drink some) and cans are just not enough to finish him off otherwise. I feel like there's a very specific amount of everything that needs to be done to make everything work, and that's a bit frustrating.
