Add New Game Features

The board now also contains 20 trolls that will take away all your treasure if you land on one!

20 distinct trolls (not on top of each other or a treasure)

User Stories

As a player, when I click on the board, in addition to a treasure or nothing, I may encounter a troll at random positions.

As a player, when I click on the board and encounter a troll, the troll is always one position in away from a treasure in the horizontal and vertical directions.

As a player, when I click on a troll, I lose all your treasures.

As a player, when the game is over, I can see where all the treasures and trolls are located on the board.

Technical Implementation

Follow the these directions:

Implement each story one at a time in the order given.

Keep each class in a separate file.

Use the CRC card format to explain in a comment right before the class definition what the responsibilities and functions of the class are. Be sure to have a Responsibilities and a Collaborating Classes sections.

Extend the BoardButton (or JButton class, depending on what you did in the first week) to create a TrollButton class instances of which are on the board

Change the look of the button when a user clicks on it: change the text or the icon
