CHALLENGES

1. Try adding new levels to the game, making sure that each one is more challenging than the one that precedes it.

2. Improve the game's skill level rating by assigning an individual rating to each level the player successfully achieves.

3. Modify the game so that it displays an icon in the System Tray whenever it is minimized. Provide the ability to redisplay the game when the player clicks on its System Tray icon.
