You cannot get all achievements of The Rewinder in a single playthrough. Instead, after clearing the game, “Harma Stone” will allow you to select chapters and get the rest of missed achievements. We recommend you to enjoy the game without the article at first, and completely missed parts later. It might take less than one hour to finish it.
