Game and reality. What is real?

After watching this film for a short time, I thought that this film was very novel. I thought that the technique of emerging reality and game was really new and funny. However, the film itself was kind of hard to take in since the film depicted the uncomfortable reality. The main character had autism and he took in the reality as a game. Maybe taking in reality as a game is his self defense mechanism, I thought. The life was harsh for him. He wanted to escape and the escape route for him was to take the reality in as a game.
