Concise horror with a very clear objective- scary setting with a cool monster. If I were to suggest anything for this game it would be to give the demon some more movement animations and maybe some misleading howls in the night to confuse the player on its position.
I played your game in my video here (and one other game) and gave more specific feedback about it. If you want, you can vote for your game on my channels community page to advance in my channels contest for best indie horror game of january. I'll be 3D printing a monster or scene from the winning game to give to the games dev!
