I just want to start out by saying... THIS GAME GOT ME GOOD! Everything from the Atmosphere, Visuals & Setting made this game a really unsettling experience! But the Sound Design is what really made me happy! It is VERY well made, and I think most horror games don't focus on it enough. Since this is a demo, I know there wouldn't be too much story present, but I honestly liked the mystery of it. Not knowing what it all means added to the spookiness.
The only thing that could of helped me in my experience, was to maybe define a bit more of what the battery you were looking for, is actually for. (ex. Find the Battery for the Camera) or something of that nature. That way im not aimlessly walking in the dark with the Camera that doesn't fully work yet. XD
Overall I really enjoyed this experience and can't wait to see what is next for the game!
