Don't make any bad move ! You may find this ordeal difficult, but think about what it is for those who come from the forest. A hard learned set of rules for them, and they have to stick to it if they want to be respected. In fact, the situation gets worse each time one of them wants to enter or leave their room, because it has no door and no window. Is there no other way out? Take the police as an example. Using traditional heuristics, policemen can spot any dead volcano -- as long as it never grows too big. This volcano in front of you, for instance, is annoyingly huge for the population.
