This article has a lot of awkward sentences that I had to reread multiple times to understand. Most of the article is a bit on the boring side. The descriptions are too wordy, and could do a better job describing what the environment looks like. More images would help as well.
I really like the paragraph about the theater rooms themselves. That part is interesting. I also like the idea that you have to avoid other people, because they could cause you to become trapped. And the subtle mention of having to kill another wanderer is quite eerie. However, I feel that the mechanics of this don't make much sense. There is no reason anyone would stay at the level. As soon as exits started to become difficult to find, they would probably leave as soon as possible. I don't see why anyone would stick around long enough that they would become trapped, unless they are really really stupid. Also, it only takes a few days before escape is impossible, so the likelihood of running into someone else while you are still able to escape seems slim.
I think this level would work better if the effect was flipped. At first, you aren't able to escape and there are no exits. Only after surviving for several days do you finally start to see exit ways, but they're always too far away and impossible to reach. As weeks pass, you would be able to get closer to the exits, and after a few months of surviving inside the level, you would finally be able to escape. But, if you run into another person who has not been inside the level as long as you, then you will quickly lose your progress. The only way to avoid being trapped inside the level is to run away from others, and as the wanderer in the article suggests, you may have to do something unthinkable to keep someone away from you if you don't want to become trapped down there for another few months. It may seem unthinkable to do something to an innocent person, but when you're almost at an exit, and you've already lost all of your progress several times before, you would certainly consider it.
