Very conceptual in both good and bad. The opening generates some good intrigue by making it pretty clear that something fishy is going on while never quite spelling it out; even as the answers are gradually revealed, recontextualizing the reader's understanding of every element propels the well-paced story to its end.
On the negative side, the conceit maybe remains a bit dramatically inert, as there isn't a whole lot happening besides just finding out how things really are. The itch description says the story is about a shift in the protagonist's understanding of the world, but I didn't really get that impression that it was that fundamental myself; it felt more like just a temporary lapse in his delusions. Like, if we're meant to take the conversation he overhears as what changes everything, surely something like that has happened before? Surely this isn't the literal first time he hears all this information?
In general, there are a couple of things like that in the worldbuilding that feel unclear in terms of what we're meant to take away – if it's the protagonist's distorted idea of what the world is like, just a narrative convenience, or something else. For example, is the lack of public transportation (if a real thing) a purposefully dystopian detail or just an excuse to make him walk around the city? When Mrs. Hunter offers to take the protagonist away, is it actually supposed to be a good thing, or is she essentially kidnapping a child (?) who also acts as the only caregiver of his disabled father? All the vagueness does add to the mystery, but as the story slowly shreds that off, the character drama would benefit from more clarity.
I feel the same way about all the fun retrofuturistic (flying cars!) touches: though they fit the veneer of naivety the plot carries initially, there's a slight tonal clash with the darker, more serious ending. Consider the television motif, for instance. Sure, "TV is a drug" is an established metaphor for a reason. But the story bets big on it as a narrative centerpiece in a way that risks feeling slightly jarring and silly in a world where linear television is increasingly less relevant as a mass media and harder to conceive of as the singular corrupting source of evil. (To be fair, I guess it would also feel silly if it was TikTok instead, but, like, in a different way.)
The game's biggest asset, and the reason I ultimately lean towards feeling like it was ultimately a pretty good read, is everything happening in the presentation. The mix of the two art styles is a good idea (though I feel like making the characters naked in the other one might have been too big of a step in abstraction). I like the music, too – it all just works really well to sell the central concept and the shifts in tone.
