Hoo, I seem to be playing quite a few cryptic games lately.
Often when a game goes more cryptic, I find myself desiring just a bit more context to at least be able to make my own conclusions, but the lack of any real answers to what is going on here was actually very effective. Less effective was the photos themselves - while they make for a good teaser of what to come, I found it rather difficult to find and recognize the things they portrayed after the first one, and I saw no real indication of the gates being open until I just randomly noticed after walking around confused for a while. Some of the fault for that is my own, I realize, but giving some hint that a new area has opened up would be appreciated.
But that's about all the criticism I have for this - it's a hell of a spooky experience, and was really fun to play. Great work.
