Earlier today I played through a special pre-release alpha demo for Through the Woods from Antagonist. It is a psychological horror game that currently has a Kickstarter underway and has also been greenlit on Steam Greenlight.
Players control Karen, a distraught mother who is being questioned regarding the disappearance of her son. As Karen begins her story, gameplay starts and players must lead her on the search for her child through treacherous and immersive environments where terrifying mythological creatures lurk in the dark.

The demo is fairly short. It was actually a lot shorter than I expected it to be, but you get not just one but almost TWO full playthroughs of the demo! The second one being a speedrun to see a special something near the end.
