If you can nail the game play mechanics of your game, then I can see it as "Darkwood" on steroids. Your game already has the ambiance of suspense built in to it. I'm fantasizing your game as a tactical based equivalent of "Darkwood". Adding the story and exploration elements to your game and you've got yourself a winner. Yeah, I would buy it on Steam.
Disclaimer: I am not a gaming expert and all of these are just my honest opinions. But I am loving your game so far.
