You have agreed with your friends that you will go to watch the Moon. Today is a special day when the earth's satellite is closest to the Earth and you can see the details of its relief. The meeting will take place at the local observatory soon and you are ready to leave, but you notice that the key to the door in Departure for the Moon Viewing Escape is missing. This upset you, you may be late, so you need to immediately start searching for the key. There are at least two spare ones stored in the house, and you need to find at least one and then the path will be open to Departure for the Moon Viewing Escape.
