I purchased this game because it seemed interesting. I'm a sucker for good horror stories.
The concept is that the dense fog in your town is rumored to kill those who have wronged others and not confessed. After an argument with a former friend, he dies, and you are the last person to see him alive.
The game is split between two main modes of interaction: deciding which of your many (well-written) friends you'll spend most time with, and deciding whether to believe in the fog monster or be a skeptic and deal with the real-life problems in the town.
I struggled with the first chapter or two, as it was more relationship-focused and I'm more into fantasy and sci-fi aspects of games. But then it picked up steam, and I ended up enjoying both facets of the game, and had a satisfying (though 'losing') ending.
