Design Exploration - Machinarium

I found this very nice game called Machinarium. The graphics are amazing and the game itself is pretty fun, challenging and with lot's of humor. I could not stop to play. The details on its graphics are impressive and the game is very intelligent. Check it out at http://machinarium.net/demo/ and try it for yourself, this is only their demo. I wish I had time to play, I would buy it for sure.
