Gameloft's Castle of Magic is an excellent adventure platform game in which you play the part of a boy trying to save his friend from an evil magician. That sets you out on a quest through pirate ships, enchanted forests, lands made of candy, ice worlds, and even space.
Actually, Castle of Magic offers 10 worlds to explore, each containing three levels and an end boss to defeat before moving on to the next world. Along the way, you'll encounter plenty of magical monsters and foes as well as jewels, stars, and extra men to collect.
The game also offers some really cool power-ups that will transform you into a swordfish darting around under water, a hunter shooting arrows in the forest, a fireball throwing magician, and a few others you'll enjoy discovering on your own.
