Implement Countdown Timer

### Objective
To enhance the challenge and excitement of the game, we aim to implement a countdown timer that will require players to complete the game within a specified time limit.

### Tasks:

- **Timer Display**: Create a timer display on the game interface, preferably at the top or bottom, clearly visible to players.

- **Countdown Functionality**: Implement the logic for a countdown timer that starts when the game begins and counts down from a specified time limit (e.g., 60 seconds).

- **Timeout Handling**: When the timer reaches zero, the game should automatically end, and the player's progress should be evaluated.

- **Pause and Resume**: Implement the ability to pause and resume the timer. When paused, the timer should stop counting down, and when resumed, it should continue from where it left off.

- **Timer Styling**: Ensure that the timer is visually appealing and that the display updates dynamically as the timer counts down.

- **Configurable Timer**: Make the timer's duration configurable, so it can be adjusted easily in the game settings.

### Acceptance Criteria:

- The game interface should include a countdown timer that starts when the game begins.
- The timer should be visually appealing and clearly visible to players.
- The timer should count down from a specified duration (e.g., 60 seconds) and stop when it reaches zero.
- Players should be able to pause and resume the timer as needed.
- The timer's duration should be configurable in the game settings.

### Additional Information:
Adding a countdown timer will add an exciting element of challenge to our game, making it more engaging and competitive for players.
