The game requires you to explore the island (turning over hex tiles but risking nasty encounters with beasts etc.), build equipment (such as rope. a basket, etc.) and build shelter (building a roof and a palisade). We were lucky -- we found a cave quickly, so shelter wasn't a problem. But we also exhausted the food supplies that were close - we never figured out how to preserve food, and we were constantly on the brink of starvation.
Fortunately we found enough wood to build the signal fire, which was the object of the scenario.
