I usually don’t like to look at other reviews of a game before I’ve written mine, but I’m going to bend that rule this time so I can check how many others managed to refrain from mentioning House of Leaves… OK, as of this writing there’s only one public review (Mathbrush’s), and yes, despite him not having read it, HoL still manages to get a namecheck. I’m a big fan of that book, and it deservedly is the first reference point when you see a house behaving the way the one in Thin Walls does – sprouting up new rooms as it starts to get full, lengthening hallways to stymie exploration, and responding to the worst instincts and desires of its inhabitants. But while the house in House of Leaves stands in relation to the individual – it’s the unconscious, a spur to knowledge and its negation – Thin Walls uses this malicious bit of architecture to take aim at society.
What we’ve got here is a multi-chapter Twine game where vignettes from the perspectives of the different inhabitants of a rooming-house alternate with a recurring, exploration-focused sequence where you can see the house changing and pick which resident to follow next. After a disorienting opening, it quickly becomes clear what unites all these stories: the anomie of modern life, and how communal living can paradoxically become isolating. The writing isn’t subtle, but it communicates its ideas well. Here’s a bit of description from the frame sequence:
"You are in a small bathroom. There is a toilet and washbasin, beside which four little soaps sit in separate containers, and four little hand towels hang on a rack and a radiator."
And a bit of reflection from one of the later stories:
"But when you move in with people and there is no relationship, any little tension becomes all that you know of them, it becomes all that they are. Just a paper doll with ‘Noisy’ or ‘Makes a Mess in the Bathroom’ written on it."
The way the house-metaphor expresses itself varies from chapter to chapter: in the most effective, it works to split up a couple who are having problems, creating space to isolate them and eventually putting up a wall between the two single beds they’d pushed together (again, the allegory is not exactly deeply obfuscated). In another, it ensures an Instagram-obsessed woman has a perfect, clean, white, sterile backdrop for all her photos. Another favorite sees a woman daydream about getting a boyfriend and moving in with him – but obsesses over the new space and the amazing furniture she’ll fill it with, until she loses track of the imaginary boyfriend and he abandons her.
By the end, I did find diminishing returns were starting to set in – the late chapter about the two housemates squabbling over who was eating the other’s cereal and making loud noises late at night reduces the house to an annoying prankster. I ran into a small bug where after I finished Chapter 4, a bit of Chapter 3 popped back up until it ended again (EDIT: I am unobservant, this is intended per the author’s reply below). And the writing does occasionally get too on the nose – at one point the Instagram lady says:
"My photos were my defence against the world, my pretence that all was well in this house."
But overall Thin Walls did a good job of keeping me engaged, and at the close of each vignette I was always eager to return to the free exploration sequence and see what had changed, who had moved in, and check whether the cupboard under the stairs had become unlocked, or the mysterious landlord who lives at the top of the house had come home yet. And the ending sequence is a return to form, with the house’s transformations becoming more and more kinetic and the social world of the house becoming unmoored and kaleidoscopic (though as involved as I was trying to solve the mystery of the house, I was also puzzled by why all the music at the climactic party was from the mid-aughts – I don’t think it’s meant to be a flashback!) It’s definitely worth the playthrough, and not just to get another menacing metaphysical house in the mental toolbox to sit alongside the house on Ash Tree Lane.
