[Disclaimer - I've played this game through many times, just not on Steam so my play stats aren't accurate]
What? You want more? Okay. On the surface of it, Botanicula resembles a highly polished version of those online "click all around the screen and interesting things happen" Flash games. And I suppose that's exactly what it is. Unlike Machinarium, Amanita's previous big success, the focus here is less on solving minigames and more on encouraging interaction and exploration. With that in mind, this game is probably more suitable for younger players (although it does get quite dark towards the end) or casual gamers.
Thoroughly charming, with a beautiful setting, fantastic incidental music, memorable characters (who again, tell the entire story without a single line of dialogue) and wonderfully inventive set pieces make this a game well worth your time and effort.
Be warned though, it does run on Adobe AIR so if you have problems with that particular application you may want to try the demo first.
