Nah. Owning the game, I don't think this is incomplete. In this "game" you touch various parts of her body and her expression changes. I have yet to understand how to make things actually progress, so to speak, as well as discover what's the player's goal: there are different outcomes seemingly depending on which part you touch the most, but aside from days (not sure, since I can't read much Japanese) advancing, nothing else seems to happen, events eventually repeat.
