# Snake-Game
The snake game is a classic arcade game where you control a snake that grows longer as it eats food. The goal of the game is to avoid hitting the walls or the snake's own body.

# How to Play the Snake Game

To play the snake game, simply use the arrow keys to move the snake. The snake will move in the direction of the arrow key that you press.

You can also press the spacebar to pause the game.
