Don't think game-play wise, outside the ability to try again, it kept strictly to the theme of "rewind". That said, game-play in a sense was a bit too easy, once you got used to 'hover cursor so the robot moves anywhere'. Also, there was a bit of a display glitch from my play-through, where the 'timer' bar ended up covering half the screen. And hindsight, the way it's positioned may be a hindrance in seeing were to go, game-play wise.
