As a small side note, this game has a nice navigation system that made me think, 'That reminds me of a game I liked a few years back.' Then I remembered that that game was 'we, the remainder' by this same author.
Anyway, this game is melancholy and gradually disturbing, reminding me a bit of The Yellow Wallpaper but also a few other stories (which I won't mention as they are spoilers).
You play as a woman wandering around a mostly-empty house, with clear indicators that you've experience many things in life (an old wedding photo, a dress that is now threadbare, etc.). The background sounds and animated color changes contribute to a mild sense of unease. One of the things that felt most off-putting to me is the matter-of-fact way the game lets you turn on all the water in the house and describes it just running and running.
Much of the game centers around alienation and also the search for your dog. More happens later on, and new NPCs mix it up a bit.
I found the writing evocative, and several sequences did a great job at 'bewildering' horror, like The Spiral entity from The Magnus archives.
Not enjoyable (intentionally so! it would be bad in a way to call this game enjoyable) but a game that I am glad I played and would recommend to others.
