I seriously hate when a character takes a significant character defining action without any build up indicating that they're capable of doing it... I've been maxing out love points with Jenny, but it doesn't matter what i do, she still gets it going with Jason... Like this makes no sense. If shes enamoured with me, it makes no sense for her to get it on with another guy in front of me, even if the Gf's nearby or not... At least build up her character and foreshadow that shes the kind of girl that would try to make a guy jealous, then it makes sense for her to do that and wont seem so out of character.

I know you're not an idiot, the game is well written and the dialogue is interesting, but you seriously need to improve chacter development, because surprises like this will turn off readers, they will feel betrayed by the character and feel that they're choices are meaningless on a game where the main focus is choosing your own path.
