It is not that common today but Darkworks released a prototype demo of their next project, a survival horror entitled Black Death. Their goal is to get as much feedback on the demo as possible so they can actually make the best possible game, and possibly the game you want to play. At a time when players blame the developers for imposing their vision of how a game should be, I think it's a pretty nice move. Of course, being a prototype, it means you can't expect every aspect of the game to be polished yet. You can find the demo and more importantly leave your feedback at this address. In the meantime, you can also watch our first video (1080p 60 fps) showing the first half of the demo and get a feel of the game's spooky atmosphere.
Update: Second part added.
