Fighting system does not have any "weight" to it (especially those finishers, they are too quick and unrealistic). Baby-eating? Why? Why would succubus eat babies? Succubus regain health through other means according to mythology. Besides, pulling baby like that would not make belly flat again in an instant.
Overall this is just a game showing off male members everywhere, just for the sake of showing them, because they can do that. If I wanted that, I'd go to some specialized website.
