The Tiny Bang Story
A gorgeous and somewhat challenging hidden-object game, with several nice puzzles and a few simple mini-games.
Well, I recommend it, but keep your expectations low. There is no story and no point-and-click adventuring: your only task is to find all the objects, and they are quite hard to find indeed! Supposedly you need to collect all the puzzle pieces, but I did not and still completed the game.
If you've enjoyed the audio-visual style here, I strongly recommend Amanita Design's games—Machinarium, Botanicula—which offer wonderful stories and much more gameplay.
If you've enjoyed the gameplay here, well, "hidden-object games" is a huge genre. There are many excellent "HOGs" on Steam. Welcome aboard!
Finally, I'd like to thank the developer for supporting Linux.
