Very nice game!
I am surprised being the only one who rated this game here. That must be because I realized afterwards that the game had been developed on Steam as well, which may have captured most of the players.
Since the very first frames of the game you will understand that this is a beautiful game.
The puzzles are rather easy at the beginning but get more and more difficult as the game unfolds. Fortunately there are some walkthroughs available on the net.
There are also some pieces to be collected (coins, pics, paintings and figurines) which are not essential to the game play but may incite playing the game again, to see if more can be found. I certainly will play it again in a few months woith pleasure!
