The Great Giana Sisters

The Great Giana Sisters is a platform game developed by the West German company Time Warp and published by Rainbow Arts in 1987 for home computers such as the Commodore 64, Amiga, and Atari ST. Players control Giana to explore a magical world inside their dreams and must find a giant diamond to wake up. They traverse side-scrolling stages while avoiding hazards such as monsters and other enemies. These can be defeated by using power-ups, which grant the player abilities such as firing projectiles and making enemies fall asleep.
