The object of the game is to navigate through the Castle to rescue the Princess.  The player can push certain objects throughout the game to accomplish progress.  In some rooms, the prince can only advance to the next room by aligning cement blocks, Honey Jars, Candle Cakes, and Elevator Controlling Block.  Additionally, the player's progress is blocked by many doors requiring a key of the same color to unlock, and a key is removed from the player's inventory upon use.  The prince must be standing on a platform next to the door to be able to unlock it, and cannot simply jump or fall and press against the door.
