Giana Sisters DS is a classic platformer. Giana is caught in a dream world and must now recover her lost diamonds and find a way to the mysterious castle. The game features more than 80 new levels (i.e. is not a one-to-one remake). There are also new special items that make use of the features of the DS. Giana can, for example, collect a bubble gum item that can be activated using the touch screen. The bubble enables Giana to fly and is controlled by blowing into the microphone. Another new feature is a world map that allows the player to select and replay levels.
