Explanation

Class Definition:
- Game class manages the game state.
- screen is a 2D vector representing the game screen.
- playerX and playerY store the player’s position.
- gameOver is a flag to indicate if the game should end.
Constructor:
- Initializes the screen with spaces and places the player at the bottom center of the screen.
Member Functions:
- draw(): Clears the screen and then prints the current state of the screen.
- input(): Checks for user input using _kbhit() and _getch() from conio.h. Moves the player left or right based on user input or ends the game if ‘q’ is pressed.
- logic(): Placeholder for game logic (e.g., enemy movement, collision detection). Currently, it’s empty for simplicity.
Run Loop (run()):
- Continuously updates the game by calling draw(), input(), and logic().
- Uses Sleep(100) to slow down the loop, controlling the game’s frame rate.
Main Function:
- Creates a Game object and starts the game loop by calling run().
