Here’s a simple Snake game implemented in Python using the pygame library. You can run this code to play a classic version of the game.

This script creates a simple Snake game where:

• Use arrow keys to move the snake.
• The snake grows in length as it eats the red square (food).
• The game ends if the snake collides with itself or the boundary.

To run this code:

1. Ensure Python and the pygame library are installed.
   • Install pygame via pip: pip install pygame
2. Save the code in a .py file and execute it.

Enjoy the game! 🎮
