Sure, here is a simple implementation of the Snake game where instead of apples, the snake eats poop. The game is designed for smartphone operation and uses pictograms for better visualization. Please copy and save the code in a single HTML file to play the game:
To play the game, simply open the HTML file in a web browser on your smartphone. The snake's head is represented by a green square ("snake poop"), and the snake body segments appear as stacked green squares. The poop is a dark brown square. Use the arrow keys to control the snake's direction and try to eat as much poop as possible. Avoid walls and colliding with your own body to stay in the game. If a collision occurs, an "Game Over!" alert will be displayed.
Enjoy playing the simple Snake game with a twist!
