You fail at reading comprehension.
Braid did far more than just rewind - which was one of its constant mechanics. Other features include:
Some levels the direction of time of everything else in the world depends on the direction you walk.
Some levels featured entities that were 'immune' to time rewind
Some levels featured the interactive 'shadow'
Some levels combined multiple of the above
SPOILER:
An example of this is one level where you actually let an enemy fall onto you, so that you 'die' and the enemy bounces off your head, then you rewind and play it forwards, again, this time jumping on the head of the enemy as it bounces off your 'shadow' previous self, to reach a high platform.
