Eventide: Slavic Fable
A charming little casual point-and-click adventure, with pleasant music and at times delightful graphics. Though the story is quite thin, it still manages to provide some character and a distinct Slavic fairytale flair.
Note that it's especially casual: the game is quite short, even when including the bonus chapter, and the puzzles are all very easy. Also, there are only a handful of hidden-object scenes, so it's not exactly a hidden-object game.
Finally, thank you, devs, for supporting Linux!
