It's free (though you can pay), so I shouldn't complain too much. It's fine, pretty short, somewhat spooky. When you're "beckoned" to the front window, it's extremely disconcerting walking towards it, I expected an Iron Lung moment every time.

But, speaking of Iron Lung, that's the game you should be playing over this. I know this is more like FNaF, but those games are terrible.
