Really creepy and a chilling take on one of the most disturbing Black Mirror episode. Bravo on making it scary without any jump scares. Superb audio design and great attention to detail in the location design.
I feel a little confused and hazy about the storyline/message though. I think I got the free will ending? Technically there's no compelling reason to comply with the messages given. The hobo that disappeared also seemed a little creepy (was he the one that got punished? Or the one dropping the phone)
I'm not a fan of the pixelated shader as it makes the text really hard to make out but I can see why that's intended (f**k was that something climbing the wall??)
