The island is empty, but not abandoned. Someone lived and worked here, and left behind their notes, their machines and their questions. Explore at your own pace, keep your own notes, and work out why you were brought here.
Quern - Undying Thoughts is a first-person puzzle adventure by Zadbox Entertainment. First released on PC in 2016 and loved by puzzle fans ever since, it is now available on Nintendo Switch too. A mechanism you learn in one building turns up again somewhere else, and the island rewards you for thinking about it as a whole rather than one room at a time.
