This game is set in a free-roaming environment. The game's world comprises interconnected areas which consist of outdoor sections, caves, water, and other thematic places with platform structures and wandering enemies. Similarly to The Dragon's Trap, the player is theoretically able to explore this world from the beginning; however, many areas are too hazardous or impossible to traverse when the player controls only one character with his limited abilities. This European version of the game has some alterations when compared with the original Japanese release such as a different story, characters' names and sprites being changed, and bird enemies dropping weights instead of feces.
