It was very P.T. inspired and it came out on around 2022 New Year's Day and also takes place around that holiday. The game was deliberately vague about what it's about and what to expect. I didn't get to finish it because I got stuck on a very simple puzzle involving angel statues representing sisters (I'm not good with puzzles in general). I understood the puzzle and its solution, it's just that the process was easier said than done for me.
