A 2D puzzle solving game, with the ability to shift time. While Prince of Persia: Sands of Time allowed you to shift time also, it was only for a limited amount of time, and wasn’t used to solve puzzles. In this game, you use that ability to solve puzzles. Some of them are hard, but not impossible — the thing is that they require unintuitive thinking — you must use time shifting fully. It’s really all you do, solve puzzles, and also follow the story.
