Snake Game Logic Overview

The Snake game works on simple logic:

The snake moves continuously in one direction
The player controls direction using arrow keys
The snake grows when it eats food
The game ends if the snake hits the wall or itself

How to Run the Snake Game

Follow these steps:

Install Python and Pygame
Copy the code into a file named:

snake_game.py

Open terminal or command prompt
Run the file:

python snake_game.py

Use arrow keys to control the snake 🎮
