I can understand that you may think the black screen is annoying, but it cuts down on file size. All the static visuals in my game are 4K, so if I were to add an image for every single black screen, the file size would increase quite a sizeable amount. As mentioned in the above description, I prefer quality over quantity.
You're also forgetting that the game caters to 5 main fetishes and 4 side fetishes, so if you're only interested in one or two, that cuts down on the amount of game play.
You do make a good point on my writing and I'm trying to work on that. Though, I honestly don't see how you think there's barely any visuals to the narration.
