The approach to 4th-wall break is very different from games such as DDLC. They would frame it as a plot twist, here it’s a fixture of the story, brought up very early on and very casually. They would attempt to “bridge” the real world with their fictional world, here it completely shifts the focus away from the fiction, and wholely redirects it onto the reader. Don’t get attached to this world, the world is not what matters here, it’s just a device to speak about ourselves. The writting’s not being subtle about it, but I think this kind of raw “honnesty” is what gives it its impact and its charm.
