Detective Work

1. Implement a start/stop mechanism for the app. (Hint: The Timer class includes a

cancel() method.)

2. Force the game to end after 30 seconds, and inform the user that the game has

ended.

3. Devise a way for users to select a difficulty level. You might want to give them

the options Easy, Medium, and Hard. You need to determine what defines the

level of difficulty. You might increase the speed at which the dot moves, make the

dot smaller, and so forth.
