I really want to start this game but I feel I would have the fear of missing things and then I will checking everything and trying to see if I should do something a certain way to the point where it becomes more of a task then enjoyment. Due to this I keep putting this one off.
Well if you do know how to manipulate saves... you can go modify the Lust values of various characters. There are missable scenes in the game if you go in an event (the event may just happen by itself or be part of a continuous chain of events.). If you don't have enough Lust points, those scenes will still happen, but the lewd stuff is replaced with nothing of sort happening to it.
Sex scenes have no animations, it ends pretty fast, its mostly descriptive... heck, at this point, I'm just in to see what would happen to the MC.
Lastly, I actually don't know what would happen if you modify the Love/Trust/Affection(what was it again? I forgot) points, the closest I can think of trying is modifying the Lust Points to make sure you don't miss any scenes. I didn't do any of this and just grinded the entire game so take notice on what would happen if you play it.
