Prince Of Persia The Sands Of Time |top| Official

The titular dagger is the heart of the game. It holds the Sands. It allows you to slow down enemies, blast them with a shockwave, or—most importantly—rewind reality. Mechanically, the "rewind" was a response to a problem: 3D cameras and precise jumping are hard. Narratively, it is the ultimate metaphor. The Prince is literally trying to take back his foolish actions.
