The game contains moderate fantasy violence, some fear/horror elements due to its dark atmosphere and undead characters, and infrequent mild language, consistent with its 'T' for Teen rating. While the story involves a kidnapping and a dark premise, these elements serve the narrative and are not gratuitous. There are no significant social or monetization risks due to its single-player, one-time purchase model.
