Who it's for, and whether it holds up.
The joke is simple: the protagonist's system dramatically overestimates everything, warning him about apocalyptic threats that turn out to be insects, rewarding him absurdly for mundane tasks. The MC refuses to believe any of it, even as evidence accumulates. When the humor lands, it's a reasonably fun gag. The "fast-food novel" label fits, and there's nothing wrong with that if you know what you're getting.
The problem is that the gag is also the entire engine of the story, and it runs on a single cylinder. The MC's persistent skepticism, repeated across scene after scene, stops being funny and starts being exhausting. There's a specific example that keeps coming up in reader discussions: the system warns about a monster in the library, the MC dismisses it, someone gets hurt, and the MC still doesn't believe the system. At some point the joke tips into willful idiocy, and the reader stops laughing with the protagonist and starts getting annoyed at him.
Dense protagonists are a staple of the genre, and some readers have a much higher tolerance for that trope than others. If yours is high, this might work fine as light reading. At 2.9, it's a story with a genuinely funny premise that doesn't have enough material to sustain it, and the novelty wears out faster than the chapter count would require.
