The game could actually have much more of the quests at this point. Instead of adding new scenes to already existing scenarios, like it's being done with Demon King, for example, where you basically submit again and again with a slight circumstances change to see alternative scenes with the same result, there could be a plotline that would lead you to different outcomes, like finding an item and giving it to her. And this plotline easily could contain some lore about the Demon Kingdom, which is given out naturally in the course of solving tasks.
Would also give some meaning to the abundance of items we have already. Like, what's the point of coming in condom and eating it right now? It could be a part of some interaction, a task to buy and eat condom for some reward, maybe a new item that gives you something. Or you could easily write a plotline that involves wearing plugs, currently they only are mentioned briefly by Brigand, Trudy, Slime, and that's all the fun. Or why giving Urka a new slave scene out of blue where she makes you autofellate yourself if you could, for example, have this option as a kind of Pacifist ending to the battle that would involve, idk, wearing a certain underwear, which would provoke her.
The only issue is adventuring between locations currently is a pain, it's a long distance to cover with expensive fast travel that isn't always available.
