You can still buy into Double Fine Adventure through PayPal

The Kickstarter may have ended, but you still have a chance to throw money into Double Fine's impressive coffers, and guarantee yourself access to both the game and its ongoing documentary. Double Fine has opened up a PayPal account to which you can contribute now -- you can find it on this very slow-loading page.

For $15, you get a Steam code for the PC or Mac version (when it's done), beta access, backer forum access, and HD streaming documentary videos as they finish. Double Fine graciously released the first episode of the documentary, which we've placed at the top of this post so you can have something to do while the PayPal page loads.
