There could be some good idea around it but I think it also could be very limited. In therm of horror, attacking personally the player is a great choice. Making horror game is some of the part making the player feel guilty about something and he will suffer from it, and making the player in that situation is hardly good for horror ( but still limited ). You'll need to learn psychology, even mental illness if you want to go very far and basically torture. As an amateur of true horror, I hope it would be good.
