Your Planet

You woke up on a planet. A small planet to be specific. Surely smaller than the moon. You may need one hour to go around the planet one time. You're completely alone on this planet without any signs of civilization or humans. The only other living beings are some animals like pigs, cows or chickens all over the planet. You see a forest, a cave and a maddow nearby. It's by you now: What will you build or make out of the planet and what secrets will you find?
