The sequel, titled simply Samorost 2, is a lot like the old Samorost...but different. Aesthetically, it's a bit darker and grittier than its breezy predecessor, as you explore the bowels of a grimy planet-ship that is home to a crew of thieving blue aliens. The main character is much more active this time, taking matters into his own hands rather than sitting back and letting events resolve themselves.
There are other changes, too. There are now multiple levels with passkeys, though the game is still short enough to be played in one sitting. There are also two chapters, only the first of which is free -- the offline version, including chapter 1 and chapter 2, costs $9.90 to download. If I hadn't just been to Target yesterday and splurged on three wonderful games I'd been wanting for just $9.99 on the bargain rack (Rhem, The Longest Journey, and Syberia II, all there together -- unbelievable!), I'd probably have bought it today...but instead I think I'll wait until January for the CD version, which will also include the soundtrack.
I haven't yet found a walkthrough online for the game, so I went ahead and made my own. It's my first ever.
What I did discover was the site of the fledgling Samorost Fan Club, which includes a discussion forum and, especially exciting to me, the complete Samorost 1 soundtrack.
It's just a special day, I guess.
NOTE: I'm having trouble uploading the walkthrough, so until it's sorted out, I'm including the walkthrough in the comments to this post. If you read the comments before completing the game, be warned! Avoid the spoilers!
