Wasn't too ecstatic upon completion,
Gonna talk spoilers here, nothing super specific, but more just my impressions as I played. I like that it went for an open-ended style, and maybe I just didn't play the game close enough to a solid conclusion, (I picked up certain things, left others, thinking some items would lead me to get a more incriminating ending, not as though I knew what the game actually had planned or how picking up those items affected my playthrough).
My main problem is that the game sets up a pretty obvious twist that your character is probably going to end up being somehow responsible for the disturbing discoveries he keeps making (and enthusiastically questioning as though he's never seen them before since he has amnesia/sleepwalks). Then the game just throws the choice to you in the last minutes of gameplay as to what happened. As soon as it hit this point I thought maybe the ending would be really dynamic, and hey, it's cool that I'm taking a small hand in the storytelling, but the choices it gave me were actually pretty unsatisfying, they changed some of the main elements of what perspired but that just made me feel like it didn't really matter much what happened, anything could've happened, there's no shocking reveal, I'm just writing the ending and then it ends, which as a mystery just doesn't work well. The ending was nothing more than a bunch of text boxes explaining my playthrough, and really hazily describing some of the decisions I made along the way. I just played the game, Home, this is old news to me and your summation doesn't make the story any less asinine.
As a Horror game it really doesn't succeed in much. There's some small amount of atmosphere but very little ever happens. I experienced a single jumpy moment when a very loud spout of steam came from a pipe in the sewers, and then nothing else happened the entire playthrough. Discovering bodies here and there was not very impactful, and I'm not even saying subtlety is bad, it can be very good, but at no point was I really given incentive to care, more often I just thought to myself "Is there going to be a cheap twist ending where it turns out this guy I'm playing is the bad guy?" and just because I can Choose My Own Adventure (Ending) so that he's not, that doesn't make the ending any better, it just makes it so neutral that I could hardly be arsed to even try to be invested in what was going on. I would try playing through again once or twice to get different endings, but to be honest the amount of walking and mind-numbingly simple button pushing puzzles and item-fetching bouts are too monotonous for repeat trips. I'm gonna call it here and say I don't recommend this one. It's a promising concept, but I'm pretty sure much more could be done with it than this in terms of storytelling and delivery.
