Willy is a mine worker. He is very much dedicated to his work and works really hard. He is so very involved in his work that at times he even forgets to go home. This proved to be a great disaster to him one day. As Willy was working in the mine, his other fellow workers have all moved out of the mine as it was time to leave. But since they did not notice that Willy was still working, they shut the mine and left. Hours later, Willy realized that he had to go home. Can you help poor Willy to cross the mine safely and go home?
