I would say yes. The most gore-y scene, unavoidable, (SPOILERS) is Gregor. Cutlets of raw human meat are also shown. (SPOILER END) and a the player has a dream of gore.
there is a note you can find from a mother begging for her daughter to be returned. the main characters could also be perceived as having been kidnapped, but I believe they came to the cabin willingly.
Not bad, but in a lot of scenes you are described as being unable to escape, and for most of the game you are described as being unable to leave the cabin.
none of the characters are confirmed LGBT of any sort, although some characters could easily be interpreted that way. either way, it wouldn't be a "bury your gays" situation
