First, it was Kickstarted. Then, it was Greenlit. Today, thanks to an outpouring of fan support, Black Forest Games' retro revival Giana Sisters: Twisted Dreams is now available for purchase via Steam, GamersGate, and GOG.com.

Giana Sisters: Twisted Dreams is a colorful side-scroller in which players must switch between two characters in order to traverse difficult platforming sequences and solve environmental puzzles. As you can see in the trailer above, each level's surrounding environment shifts dramatically whenever you change characters. The background music follows suit, smoothly transitioning between a Chris Hülsbeck-composed chiptune soundtrack and metal remixes from Machinae Supremacy.

Giana Sisters: Twisted Dreams is regularly priced at $14.99, but is available for $11.24 during its launch week.
