Do your dialogue options make a difference in the story? Seeing images in the preview that i never saw before. Or are these to show upcoming routes and scenes?

Ha, thats fine, what i played was amazing!

was wondering how much of the game there is? Ive been playing for a bit and beat the mushroom boss for the first offering, but adter that it doenst seem like there is any way to progress after walking around for quite a while looking for new zones.
