After coming across a youngster Let's Playing The Trapdoor, and also as a trigger warning, I feel compelled to offer the following statement, especially since the inital inspiration for the story was extrapolated from a children's TV show:
Like Amnesia: TDD itself, The Trapdoor deals with some adult themes. As well as the usual Amnesia fodder, this also includes brief references to domestic violence, misogynistic views and not-so-healthy sexual relationships. This is part of the story: the views of the character are not the views of the author.
Remember that, like movies, books, etc., not all games are meant for kids to play.
