Giana Sisters: Twisted Dreams is slated to come out for Linux later this month. A post by a developer at the end of November confirmed that the game is on track for a release in December.
About the Game
A self-described 'hardcore platformer', Giana Sisters: Twisted Dreams combines colorful stages and character design with some apparent solid gameplay. Giana Sisters: Twisted Dreams was the result of a successfully-funded kickstarter campaign and is, in fact, a sequel to a popular late 80s platformer. As part of its core design, the game features the ability to switch the mood of the stage on the fly thus affecting enemies and obstacles. The music is also noteworthy, with the original composer for the series returning and his work being alternated with heavy metal arrangements whenever the mood of the stage is switched by the player.
The game was featured in the Humble Indie Bundle 11 and has been out on steam for about two years, but it's good to know that it's finally coming to Linux now. The upside to waiting is that free content has made its way into the game over the years; the last big patch added a competitive multiplayer arena race mode. Finally, as always, please only purchase the game when it's officially out for Linux so that the developers can see that it was worth their time and effort to bring us the port.
