Something of an homage to the original Super Mario Bros., Braid puts a twist on the classic side-scrolling platform game by allowing players to manipulate the flow of time in order to solve puzzles and rescue a kidnapped princess. Each of the game worlds offers players a different time-warping ability, from rewinding time, to creating a parallel universe, to setting up pockets of dilated time, and each ability helps gamers collect scattered pieces of a jigsaw puzzle. Each level features backgrounds made to resemble Impressionist paintings, and a running soundtrack of classical music provides ambiance.
