Well based on looking at his account (since the review is seemingly gone), I think I have a pretty good idea what he complained about, and clearly he's a bit of a tool and quite possibly an incel. So to answer your question, a good number of things
.
If what I assume the "review" covered is right (probably whining about pronouns and not-cis people existing and the fact that this game is violently cute), then that's the sort of thing I'm honestly surprised there isn't more of that here, given this site and the bulk of its community. I enjoy the little oasis these games have here, though I'm kinda baffled that other people who'd like these games are on the site period.
