Cool concept!
I think it looks great and that helps set the atmosphere for this game.
I had some issues controlling the light - for me the camera movement was a bit too quick and I ended up going left-right-left-right to somehow get to the middle, but besides that it was a fun experience, well done :)
It's not an issue, it was just moving too fast for what I expected.
Clicking ahead and slightly to the left, for instance, would move the camera, quite fast, far more left than what the click was.
So basically going slightly left or right made the camera go to the same direction but much more "heavily". I think it made the movement a bit more harder to control, that's all.
