So not addressing the other comments, but as someone that lives in the northeast of America, no I've never heard anyone speak about this game, or seen anything about it online or in person, outside of actually looking it up on itch or patreon. It's probably just a regional thing, or just another passing fad. Everyone lost their minds over Yor when Spy x Family came out, and now it's onto something else. The particular community you're referring to probably just gravitated towards the character because of either the character itself, or just because a sizable chunk of like-minded people shifted onto the game and started talking about it.
