Love the psychology of the characters in this game, as well as the tense atmosphere and engaging twists.
I do feel a lot of the endings were rushed, the "Anna/Jack" ending being the one exception (and I did see you comment that it came out the most naturally?). I also feel it would have been interesting to see events from Grace's POV, especially since we already see from the other two main characters.
Overall, an engaging visual novel. Definitely one of my favorite video games of all time.
