Wikipedia:Articles for deletion/HyperRogue
I don't know, this seems like a really marginal case. In my searches (books, scholars, sites), I haven't found anything reliable that wasn't already mentioned by OP or that it's in the article. I have removed countless of random blogs and community writer pieces on reliable sites like Gamasutra/HonestGamers from the reception section. That leaves three sources, all of which I'll try to analyze now. The first one is Rock, Paper, Shotgun one at https://www.rockpapershotgun.com/2017/09/28/hyperrogue-non-euclidean-roguelike/. While the source itself is reliable and the text is in-depth, it doesn't tell much about the game at all, and it's mostly a commentary.

And there is a really great in-depth scholar coverage, co-authored by University of Warsaw's staff at http://roguetemple.com/z/hyper/papers/hyperrogue.pdf.
