The "Kingdom Hearts" games are divided into various game levels, referred to as "worlds", which the player progresses through over the course of each game. Worlds vary in appearance, typically dependent on the Disney setting which they are based on. The worlds' graphics resemble the art style from the originating Disney film and the worlds are inhabited by characters from their respective films; for example, Hercules and Philoctetes appear in Olympus Coliseum from "Hercules", while Aladdin, Princess Jasmine, and the Genie appear in Agrabah from "Aladdin". The game worlds consist of interconnected field maps where battles and plot-related events occur. Players travel between worlds in different ways each game, such as the "Gummi Ship" in the original "Kingdom Hearts", "Keyblade glider" in "Kingdom Hearts Birth by Sleep", "Corridors of Darkness" in "358/2 Days", and "Sleeping Keyholes" in "". Worlds created specifically for the series mirror the overall appearance of the other worlds and predominantly feature characters from Square Enix games and original characters.
