Snake Game

This code provides a basic implementation of the Snake Game using JavaScript inside a single HTML file. The game can be played on a smartphone by using the arrow keys to control the snake. The game canvas is represented by a green square for the snake, a red square for the food, and a black text to display the score. The game ends if the snake collides with the wall or itself, and the player's score is shown in an alert.
