Do repeat gifts give less points than new ones? I've given so many gifts that there just aren't enough to satisfy each of their individual likes. I've started giving repeat gifts because they still seem to like them and I may make some progress but not as much as before. Also, why does it say that I am far from developing a relationship with a character even though the day before it said I was very close?
The repeated gifts DO give less points. I'm unsure when I changed it so that the decreased value is less harsh but eventually I did that. How it currently works is that the gifts will have a base value based on who you give it to and if it's the first time you've given it to them and you like it, the value is multiplied by 3, if it's a neutral gift and they like it, then it's multiplied by 2. If they hate it, the value is 0 points.
I should also note that as new updates get released, more gifts are added and there'll be more options for every character so repeat gifts will happen less and less.
That second part may be a bug that I'll check out. It's like a logic loop where when the points reach the target, it resets back to 0 and allows you to proceed to the next chapter, thus when you give a gift, technically you've leveled up the relationship but the closeness is back to 0. If that's the case, it might mean you need to talk to them in a different room to trigger the new chapter.
Hope that helps.
