I prefer visual novel-style gameplay. It's fine to include some mini-games, but they shouldn't be too difficult, otherwise it feels like the focus has shifted away from the main point.
I would, after all it's me who wants to fall in love, not watch someone else fall in love. So if the heroine's personality is very different from mine and hard to project onto, it really cuts down on the appeal.
I have very little patience and always want to reach the ending quickly, so I don't like storylines that take too long to unfold. But I don't mind if the sweet content after the ending runs a bit longer, haha.🤣
