I stumbled into Monument Valley over the weekend and I'm hooked. This game follows a princess as she works her way through a series of intricate mazes and castles with levers, pulleys, and physics-defining ingenuity. You know those contraptions in the opening credits of Game of Thrones? It's like that but not nearly as ominous. In fact, one of the things I like about the game is that there is no dying. Just some puzzles, a princess, and the occasional squawking bird. I've been taking my time with each level and really enjoying it. You can get Monument Valley in the iOS App Store.
