Unlike in most of the Adventure games, the Sapiens player isn't confined in predefined game schemes. The freedom degree is total: you can move everywhere you want, at any time, and you can do absolutely what you want.
In Sapiens, there is not only one way to succeed. Everyone have to find his way, depending on his own nature. The knowledge of the environment is an important point, so don't hesitate to explore the territory to learn where the springs, the plains well-stocked in rabbit and the other tribes are.
The Sapiens freedom makes the advices a bit ridiculous. Have we to say that you must drink when you're thirsty, eat when you're hungry and sleep when you're tired?
