Absolutely terrifying. My hands are still a bit sweaty.
I was so on edge the entire time. Alex's unusual demeanour and uncanny eyes, the background music, the slow build of tension, the incredible art... brings me back to 2012 when I was 11 and discovering Slenderman, smile.jpg and the Russian Sleep Experiment. I don't want to spoil anything, so I'll just leave this quick video here so you can laugh at how much of a wuss you made me.
