I think I've seen a similar mechanic in the critically acclaimed side-scroller Braid [1]. There's a world called "Time and Place" where the flow of time is tied to the player's horizontal position. Going right and left takes you forward and backward in time respectively, and standing pauses it. Amazing game, really.
Also, a new game from the creator (Jonathan Blow) is scheduled to release this year, The Witness [2].
