Island Travel Time

There are three things about this island that are not written in the entry manual. First, time is currency. Every second you spend is a qualification to live here. Second, people who are at zero will leave. No one discussed where they went. Third, I'm looking. Before enrolling, I thought graduation was the only problem. Later it turned out not to be the case. The real problem is - you never know when time will turn back. And whether you can still stay awake after you look back. Most people won't wake up. But the question is never whether to wake up or not. The question is, when you wake up, where do you go?
