Suggestion, how about a sort of achievement system for some bonuses that carry over between plays like starting with a 3rd gift or being able to create and encounter your own heroines.
I don't think I need to explain my reasoning for wanting the ability to make custom heroines but the reason for wanting a 3rd gift is cause there's alot of gift options but it almost feels required to grab a gift that affects quest drive to keep the heroines around long enough to start making money and progress in a reasonable amount of time.
