The plot and game really breathtaking, but after i finished campaign is it all? I mean why we collected red hearts for girls , and i didn't meet scenes with direct H. Can i continue playing after, finishing campaign?
There's no new game plus, though the story has some branching parts; you can start from scratch and maybe get another ending. I assume with "direct H" you mean vaginal sex? If you haven't seen any vaginal sex, you missed quite a lot! You should definitely have another go. If you wish, you can use the official walkthrough or a mod I made that provides guidance as you play.
