The game's story effectively captures a horror vibe, creating an intense atmosphere where players feel the weight of their characters' struggles.

The multiple endings and choices provide substantial replay value, allowing for varied experiences and outcomes, though some elements may lean heavily on fantasy romance tropes.
- “The game captured the horror vibe very well, and for nearly the entire story, I was just waiting for my character and the group to catch a break. It made the story feel really intense at parts.”

- “Rather than offering spectacle, it invites players to immerse themselves through imagination, moral tension, and a constant sense that every choice—large or small—can echo throughout the story.”
- “I feel like it didn't really resolve much, and the secret ending especially just sort of ends without paying off a lot of the major story beats.”
