If you haven’t played Braid before, here’s what happens when you turn it on: It looks like Mario, but something is wrong. You’re a red-headed guy wearing a suit, for one, and the music is not the old Mario song; it is, in fact, quite sad. You run to the right, just like Mario would, hopping on enemies and over man-eating plants popping out of pipes. At the end of each level, there’s a flag, a castle, a dinosaur. But at some point, you will inevitably die, which is when the game springs its core provocation: One pull of the right trigger lets you rewind time as much as you want, right back to the beginning of the level, if you choose.
