W.I.T.C.H. is a platform game for the Game Boy Advance. It was developed by Climax Studios and released in Europe on 7 October 2005 by Buena Vista Games and Disney Interactive Studios, Inc. The game was not released outside of Europe.
Although the box art resembles the look of the characters in the comic book, the game's storyline and graphics are based on season 1 of the animated television series based on the comic also called W.I.T.C.H..
The game is divided into chapters, in which there are stages. Each Guardian has the ability to fly as well as two unique elemental powers. Players are able to switch between the Guardians at any time (Will is the default guardian). Players can also combine the powers of any two guardians except Will to destroy all enemies on screen. However, using elemental powers and flying drains energy from the Heart of Kandrakar meter displayed at the top of the screen, above the health meter. Likewise, when characters endure damage bars from the health meter are lost. Caleb is also playable in his own more action-oriented levels. He can use a sword and longbow. Blunk is a NPC who trades you useful items for something he wants. Needed items can be stored in the inventory. The game has 20 levels in total. After beating the game, the player unlocks Kandrakar Mode, which allows each Guardian to use her abilities without drawing power from the Power Meter and gives Caleb unlimited arrows.
