Because the game raised so much more than expected, the Double Fine Adventure will now be coming to PC, Mac, Linux, iOS, and Android. There will be a DRM-free version available after it's released. It will feature English voices and subtitles in English, French, Italian, German, and Spanish.
There's still time to support the Double Fine Adventure, and get in on the pre-order bonuses, such as a private beta on Steam, a video documentary detailing the process on making the game, and a private backers forum to discuss the game as it's being made. There's also bonuses if you want to pay more than the $15US minimum, such as high definition download of the documentary and the soundtrack in digital form for $30US, and a poster of the game and your name in the credits for $100US.
