Frankly I got very bored with it and did not finish. Maybe it's because I've never felt "existential dread" or maybe it's because I had already run into and come to terms with the Teletransportation paradox as a thought experiment so the concept wasn't new, but the horror completely missed me so all I had was the walking around and getting increasingly frustrated at the character's ignorance. I looked up the plot synopsis after I had enough and it's just... yep.
