Yeah, at some point I guess I should write a whole unique paragraph about it. For now, I'm adding some news stories that'll hopefully build the world and help improve the experience. Thanks for reaching out, it really helps!
As for adding further interactivity beyond push-button-get-bigger... I'm not sure about that. I could make it push-one-of-several-buttons-get-bigger, I guess. In doing so I may even be able to make the vore itself optional, as I know that significantly reduces the target audience. Things to do after I get the first update done.
