This game is a lot of things all at once.
Perhaps the majority of it is wish-fulfillment, of a sorts. Your character is a nervous, self-doubting trans woman with major executive processing issues, and the biggest storyline is about a girl you've had a crush on for years turning out to have a crush on you too and the two of you flirting, with her being deeply accepting of everything about you including your transness and disability. This is contrasted with your family and society (represented by an institution) who accepts neither of these things.
Overlayed on this is another storyline, that of the world having already ended and a messenger of light from Hell (I think?) having become entangled in your dreams.
Overall, the game does a good job of sketching distinct characters and their personalities. There were enough small typos here and there to be noticeable (wish I had written them down, but forgot). There are some bursts of strong profanity, mostly used to express anxiety (including the first screen). The game has a lot of references to attraction and making out but is generally non-explicit except for a segment describing the character's own body, from the lens of their satisfaction (or lack of) with her appearance.
Overall, I think this game appeals most to one's sense of longing for acceptance and belonging, which is fairly universal. And in that sense, I would say it's a successful story.
