I really like this game, accepting that the characters are youngish looking, it doesn't make me want to suddenly become some weird predator.
The game is about incest, or the chance of, clues in the title, so if you think "ah my daughters 18 now - game on" you probably are slightly touched in the head and not really in a position to be moralising about models looking younger than 18 (when clearly stated they are not) and should stay well clear of incest games.
It's fantasy, pretty well written and good fun.
More annoying is in chapter 2 my skype call in the hotel has 3 options and then I am unable to progress the game, and she needs rescuing from that pink bedroom, probably.
