The SNES port of Prince of Persia 2 is generally regarded as a bad port of a very hard platforming puzzle game. The controls are clumsy, the puzzles are seemingly random, and the player dies very easily. The port also leaves out the last level. Fortunately there is a major bug in the game that allows large parts of it to be skipped.
