The CD version of Samorost 2, containing both chapters and the soundtrack, is finally here, available at the Samorost Cafepress shop. As soon as I learned this fact I immediately bought it, along with a cute Gnome mini-button. Everyone should go out and buy the game right now -- support Amanita Design so we can have a Samorost 3!
The soundtrack was a nice surprise compared to the original -- it has twelve tracks and is a full forty minutes long. And the music, of course, is great.
I finally got to sit down today and play Chapter 2, which was wonderful but naturally far too short. And I was finally able to complete the second half of the walkthrough I started. You can view the whole thing at my original post: Samorost 2 Complete Walkthrough.
