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.
It's an incredible, revolutionary puzzle platformer. There is no other game like this, no Limbo, no Anti-Chamber, not even Portal. (Portal has other strengths that Braid does not have, but the puzzles in this one are even stronger.)
The game's not flawless, the graphics of the main character and enemies are a bit daunting and the story is very much up it's own a**, but none of this makes the puzzles less genius.
Everybody *needs* to play this game, no matter what.
