Giana Sisters DS is a side-scrolling platformer where you guide Giana through a dream world to recover stolen diamonds and explore a mysterious castle. The game features 80+ levels built specifically for this release, not ports from earlier entries. Core mechanics include standard platforming—running, jumping, collecting—but the DS hardware adds unusual twists. One power-up lets you chew bubble gum, activated via the touch screen, which inflates Giana into a floating state. You then blow into the microphone to control her flight direction and duration. Other special items appear throughout but aren't detailed in available info. A world map lets you choose levels freely and replay completed stages. The visual style leans colorful and cartoon-like. If you're comfortable with gimmick controls that require literal breath input, this offers a full-length platformer designed around the DS's specific capabilities.
