I made some cosmetic changes to the game and also added a "hall of fame" of the ten best scores. I actually sit and just play the game at times.
I got bored with the game grid being all one color so, I added a color item to the board grid record and set each square to a random color (except dark blue and black) when the board is first initialized. When a block shape is placed on the grid, the colors for the grid squares are predetermined.
