UPDATE: I GOT THE ENDING (10/19) so beautiful I think thats my favorite ending I loved the join me in death by HIM song ref
YESYES I GOT YOU (SPOILERS FOR OTHER PEOPLE) So at the beginnging when you get to roam around the house, you get the option to grab the plate and break open that cabinet in the living room, which gives you the cigs. Instead just all together dont grab them, and after that only ever pick the dialogue options that make the pale guy content or happy.
Then after you meet all the other visitor the pale guy is gonna ask if you want to go on a walk, say you want to stay, and then he'll ask if you want to smoke. Once he comes back pick the option "Of course!"
I dont want to spoil any of the dialouge for you if you havent read it yet! But in order to get the ending pick the options "What I have for you" and "I want to kill you" That will cue the 10/19 ending!! IM STILL FINDING NEW DIALOUGE THIS GAME IS SO WELL DONE I LOVE IT
