Machinarium is a point-and-click adventure game from the same developers as Samarost. It's available directly from the developers, with soundtrack bonus, and on Steam. I got my copy with the Humble Indie Bundle—which is no longer available, but if you like these sorts of games I'd definitely sign up for their mailing list because it's always a great mix of games at pay-what-you-like.
Machinarium has a bit more of a narrative than the Samarost games, which you discover as the game progresses. It also solves some of the click-everywhere puzzle frustration of the earlier games by introducing the restriction that you can only click places that your little robot protagonist can reach. Cuteness levels remain dangerously high.
