Czech studio Amanita Design (Samorost) has posted playable demos for upcoming PC/Mac game Machinarium, releasing on October 16th. In the IGF-winning puzzle/adventure title, you play as "a little robot who’s been thrown out to the scrap yard behind the city [that] must return and confront the Black Cap Brotherhood and save his robot-girl friend."

You can download the free PC demo from Big Download and the Mac demo from GamersGate. Amanita also put up a preview of Machinarium's soundtrack composed by Tomas Dvorak, allowing you to steam six excellent songs from the game.

Don't forget that you can get $3 off the release's $20 price if you preorder Machinarium!
