Previous Day in Lighthouse Game

The lighthouse is the tower which lights up at night to guide ships passing nearby. In this game we are situated in the tower to solve the game. One day the controller was early for work. He decided to relax for a moment and take a walk along the sea wall. When suddenly he got something from his pocket and did not notice the keys fall. Time for work and he climbs up the house and started his shift. He decides to lock the door and sleep. He woke up and noticed the keys are missing. Help him find objects to solve puzzles and get out the tower. Good luck!
