i have a idea how about add opportuniti to upgrade youre store and like that player can have choice what kind of stuff (for using on girls) will be added to shop, not in the sense of opening the content yourself, but let's say something additional to what you already receive from day to day, let's say now a potion for enlarging the butt and hips, this is one potion, in a word, it will add upgrades, because why do you need money if there is nowhere to spend it?
