Indie developer Black Forest Games announced that its Commodore 64-era revival project Giana Sisters: Twisted Dreams has crested one million sales units across all available platforms.

Funded by a successful Kickstarter project, Twisted Dreams is a dimension-shifting platformer that launched in 2012 for Windows, with ports for the Xbox 360, PlayStation 3, and Wii U arriving last year. Black Forest's recent sales milestone comes in the wake of Twisted Dreams' recent appearance in Humble Indie Bundle 11, where it accompanied standout indie hits like Guacamelee, Monaco, and Dust: An Elysian Tail.

Black Forest continued to update the Windows version of Twisted Dreams with new content in the years following its initial release, including holiday-themed Christmas and Halloween levels.
