I wouldn’t read into it too much. The author posts almost every day on all kinds of minor topics related to geeky media, and it includes various gaming experiences. I found her posting about Tales from the Loop, for example, and other games.

Probably she played this game with her husband and some friends, and then wrote about it (like she seems to have done with lots of other games she’s played).

…or is there a reason to be particularly worried here?

(Not that I would ever play Mirror, having said that…)
