That game has genuinely been pushed/name-dropped on Youtube harder than any other game I've seen recently. (Aside from things like Among Us, or actual paid mobile games ads ala, Raid Insert Title Here.) To the point that I can't help, but it having the opposite effect on me...

Vampire Survivor looks like it uses slot machine tactics to keep people playing. (The dev supposedly worked in the gambling industry.) So the game uses lots of noises and flashing images of money on screen, etc. Just without the microtransactions, and endless spending that usually goes along with it. Thus, mobile game addicts or whales like most of the streamers who gave Blizzard all of its free advertising, are now playing that and praising it to high heaven.

But it appears that the game is essentially a mindless clicker game, without any input from the player aside from moving around. So, I can't say that kind of thing appeals to me.

Though upon further looking into it. I guess the dev is at least transparent that this game was already being developed to be a clone of another free-to-play IOS game. "Magic Survival" (So I guess his goal was fairly successful...)
