This is one of the best stories about deep, deep mental illness I've seen. Time and time again I've found myself intensely empathising with the author, because there is no way you'd write psychosis, derealisation, loneliness and fantasizing that well without being intimately personally familiar with them. If I were a video essayist, I'd make a video about this longer than the runtime of the game. Of multiple runs. Because it deserves a thorough, empathetic dissection of all of the mental health themes scattered throughout the story.

And somehow, it avoids being pessimistic and cynical. You can see hope for the future shining through all the muck the protagonist is held down by. Even though she's in deep, deep ♥♥♥♥, and has been in even deeper ♥♥♥♥ in her life (something you can find out if you press her repeatedly on it - which is, again, very realistically written in how you unearth memories your brain deeply suppressed). Unless I missed something, she's not even that bogged down by S thoughts regularly - she constantly fantasizes about escaping her toil because she wants things to get better, not because she wants herself to end. There is constant self-loathing in dialogue, yes, but that feels more like force of habit than something that affects her a lot. I am very familiar with that behaviour pattern both in myself and in people I've known.

The game has a couple of endings, and I encourage you to look up a 100% Achievement guide to get them all (that should stretch your game experience to about 3 hours, I've only got more because I've beaten this game twice last year). Some are unfortunately clearly worse than others, and while I won't list them all here, I want to shout out:
Everything Is Fine Ending (or the Mirror Ending) - great portrayal of derealisation and self-image issues with minimal communication means and a healthy dose of good ol' horror. The exact same dialogue repeating every time reinforcing the idea of just how everyday dealing with those issues was to her, even when she was functional.
The Shop Ending was a bit unremarkable to me since it's just a musing on the first game's story... but the moment the girl wakes up makes it an instant classic for me. In fact, that's what cemented for me the idea that the girl is still very much hopeful for improvement: no matter how good or bad the Ending you get, she's still getting a dream when she hasn't dreamt for a LONG while and that makes her tear up as soon as she wakes up - in my opinion, those are not despair tears, those are cathartic tears. She may still have nightmares, she may still have nightmares each time she goes to sleep.... but at least she's having them while asleep, not while derealising while awake and just flying off the handle of reality into vivid images of her own torture and death.

MoaBoM is ultimately a story about getting better through finding a good coping mechanism that works for you. I don't care how "cringe" you think it might be, but if pretending you're a protagonist of different genres of games, or pretending you have a friend in your head* gets you through your day? Then I say you ♥♥♥♥♥♥♥ do it.

*or, in the protagonist's case, she might have actual DID, who knows.

I got i because i thought this was a psychological horror. Instead i got depression and overthinking having to comprehend the inner machinations of my psychy. 10/10

This was agonizingly great. The soundtrack and sound design are eery and captivating, the art style is fully realised, and the writing is sharp, surreal and on point that it's easy to peel it off and start understating the many layers it covers itself with.
