Adventure Night Forest

You went to study in a driving school and today you will have a night ride. The night was very cold and foggy. Through the fog, you are not considered a tree in front and crashed into him. Your instructor ran to seek help in the nearest villages. You came out of the machine around and saw only forest. You walked a long way through the woods until they found a house hunter. It seems that no one is inside. You must find the key to the house.
