Oh my god I love this thing. Absolute banger, author is a genius. Incrediblysad that games like this don't get mainstream popularity, because in my opinion games like these reflect the real potential of games as an art form more than any shooters or RPGs.
Atmosphere is actually chilling. Almost nothing is said explicitly, and this only adds to the experience. The game is barely 15 minutes long, and at the end I almost cried. So many games nowdays stretch the playtime to hundreds of hours and don't have even a smidge of what this has to offer. Bravo, that's exactly the experience I looked for when I entered "surreal" in the tags.
