A simple implementation of the classic Snake game in C. The game runs in the console and allows players to control the snake using the arrow keys.

• Food Generation: Randomly placed food that the snake can "eat" to grow.
• Collision Detection: The game ends when the snake collides with the walls or itself.
• Game Restart: Press 'r' to restart the game after a game over or win.
• Difficulty Levels: Choose between Easy, Medium, or Hard difficulty that controls the snake's speed.
• Score Tracking: The score increases as the snake eats food and is displayed in the top-left corner.
