Halloween may be over but that doesn't mean you can't play a horror game here and there. The Last Door is an episodic horror point and click adventure game that's free to play on thelastdoor.com.
It's a sort of Lovecraftian style of horror, which I like, and doesn't really rely on jump scares. As of this post, chapter 1 and 2 are free to play on their site. Chapter 3 is also currently available but will be free to play on January 2014. If you want to play chapter 3 early, you can donate a bit of money to the developers at http://thelastdoor.com/index.php/donate. They also have a few incentives if you donate certain amounts. The Last Door is also trying to get on Steam Greenlight.
We did a short Let's Play of the chapters 1 and 2 that are currently free. Check them out. If you like how it looks, I recommend you try the game out for yourself.
