Oh, what a beautiful thing this is shaping up to be. You can now play the first three levels of Machinarium, and find out for yourself why Amanita Design's latest hand drawn adventure is filling us with so much hope. The demo is available from here or here, and the full game is due to be released on the 16th October via Steam, Direct 2 Drive, Impulse and so on. Most of those places are taking pre-orders now, and while I've not played the finished game it's a pre-order I feel fairly certain will be well invested. There's also a new trailer below.
