Braid is a puzzle-platformer, drawn in a painterly style, where you can manipulate the flow of time in strange and unusual ways. From a house in the city, journey to a series of worlds and solve puzzles to rescue an abducted princess. In each world, you have a different power to affect the way time behaves, and it is time's strangeness that creates the puzzles.

The overall gaming experience is very good, but what really hurt my opinion of it was the secret stars. The ways you obtain them are so far out there they defy the basics of designing a game. (Making a player stand still for two hours, making one star unobtainable if you complete world 2 and 3's puzzle, etc) The creator made such blatant bad decisions that I wonder if he didn't do them on purpose. In any case, if it weren't for that, I'd give it a 10, but not being able to 100% a game, or even know about the secrets in the game without getting a walkthrough or being a seriously dedicated player, is insane.
