When you access PrinceJS, 'Press to Start' is displayed as shown below, so press any key.

Then the opening movie is displayed, but you can skip it by pressing the key.

The story of Prince of Persia says, 'A young man who fell in love with a princess in the Kingdom of Persia was imprisoned in a dungeon by Jafar, a minister who plans to marry the princess and take over the Kingdom of Persia, and was trapped in the royal palace.

You can see how you are actually playing in the video below.
