It's a really enjoyable platformer with lots of great features and two flaws.
The story is good, the prince's wall-walking, pole-vaulting acrobatics are impressive, and the ability to rewind your blunders fits so well with the genre you wonder why nobody had though of it before.
But the combat system is cheap. Learn a simple technique and you can defeat three quarters of the enemies in the game. Learn a second one and you can defeat all. Fights with multiple enemies can be tricky, but it always the same two moves over and over.
Secondly, the replayability value is low. Once you finish the game, that's it - you know how to solve the puzzles and surely you won't replay for the combat, right? Additional difficulty levels or some trick modes would really be useful. But since you are buying the game cheap, it doesn't matter that much.
