[SPOILERS]
I'll be honest, I didn't like how the whole backstory was spelled out at the end like it was, I think that made it sound really cheesy and took me out of the game. But the game itself is great on an atmospheric level, I felt every bit of the loneliness as I wandered back and forth, and by the end I felt a sense of dread every time I turned a corner. I'd love to see more like this, it's a simple concept but executed very well, with the exception of the "supernatural/haunted video game" backstory.
