In the Hairy Harry game you control a little funny man called Harry. He was sent to prison by a mistake of the unjust law and has to escape to prove that he is not guilty... To escape the prison Harry must pass through all of its levels. At the end of each level there is a steel door. To open this door Harry must collect the keys to all its locks. The number of keys left you can see in the information panel at the bottom of the screen. In addition to the steel doors there are also secret stairs that also open Harry the way to freedom as soon as he collects all keys. The prison guards and specially trained rats will pursuit Harry on his way to freedom trying to prevent him from escaping the jail.
