This one's not nearly as pretty as the third and final demo, but it's probably the most full-featured of the three demos. This one contains more content (starting from the initial sequence with the pull-chains, through the falling scene, and giving you a bit of reflex-based action and a "boss" battle). If you edit the game, there are also a couple of incomplete cinemas to watch.
