Prince of Persia is a fantasy cinematic platformer designed and implemented by Jordan Mechner for the Apple II and published by Broderbund in 1989. Taking place in medieval Persia, players control an unnamed protagonist who must venture through a series of dungeons to defeat the Grand Vizier Jaffar and save an imprisoned princess. Much like Karateka, Mechner’s first game, Prince of Persia used rotoscoping for its fluid and realistic animation. For this process, Mechner used as reference for the characters’ movements videos of his brother doing acrobatic stunts in white clothes, and swashbuckler films such as The Adventures of Robin Hood. Gameplay: The main objective of the player is to lead the unnamed protagonist out of dungeons and into a tower before time runs out. This cannot be done without bypassing traps and fighting hostile swordsmen. The game consists of twelve levels (though some console versions have more). However, a game session may be saved and resumed at a later time only after level 2. The player has a health indicator that consists of a series of small red triangles. The player starts with three. Each time the protagonist is damaged (cut by sword, fallen from two floors of heights or hit by a falling rock), the player loses one of these indicators. There are small jars containing potions of several colours and sizes. The red potions scattered throughout the game restore one health indicator. The blue potions are poisonous, and they take one life indicator as damage.
