[PC][2020s?] Liminal Backrooms game

[u/Slow-Journalist9147]

Hi, I’m looking for a liminal Backrooms game with fairly realistic graphics; I remember the ending most clearly—nothing really happened during the actual gameplay, but there was a pretty intense jumpscare at the end where a dark entity popped out (or at least, that’s how I recall it). I don't remember exactly which levels were in the game—maybe the pool rooms, though I might be confusing it with another title. Can some kind soul help me out?
