Giana Sisters: Twisted Dreams, the Kickstarter success from Black Forest Games, officially launched today for Xbox Live Arcade at 1200 MSP. To celebrate the release, the studio has issued a new trailer for what should be a great addition to the XBLA library.

Existing inside a dream world, Giana Sisters: Twisted Dreams has you make your way through vibrant platforming levels, while taking advantage of your transformation ability to solve puzzles and defeat enemies. Transforming allows you to immediately switch between dreams and nightmares, which is essential for clearing obstacles and progressing through levels.
