The sun has heated up and people called Visitors have risen up to the surface. Stay inside and let people live in your house... if they're humans. Use arrow keys to move in all 4 directions. Use the SPACE key to interact with objects. During the night you should check the door and let people in while during the day you spend your valuable energy to check people to see if they're humans or visitors. If you want to waste energy, go to the table and click SPACE to drink some alcohol once you select it using the right arrow key and become tired. After a few days the guests will move out of the house to continue with their lives. Every few days you might restock on consumables like Purple palm tree delight which increases energy.
