I saw the comment that there are multiple endings based on what you do, but I couldn't really find too many "different" things to do. Despite being short, I really liked this one, and it's the only game that gave me the creeps so far. The music was a bit annoying at first, but then I realized its discordance was part of what was making me feel so ill-at-ease. I would have liked this to keep going, because it was really creepy and atmospheric, in a way I haven't seen too many others be. I also saw the original videos, and some of the YouTube "theory" discussions about them. While it's all really good, the false alarm from the government at the beginning of the series was the creepiest thing I'd seen for a while, and this game did a really good job of keeping that same uncomfortable feeling of "something's not right."
