Sure! Here's an example of a simple Snake game implemented in a single HTML file using JavaScript. The game should be playable on a smartphone and uses pictograms for better visual representation:
To play the game:
- Copy the above code into a new `.html` file.
- Save the file with a `.html` extension (e.g., snake.html).
- Open the file in a web browser.
- The game should automatically start. Control the snake's direction using arrow keys.
- The goal is to eat the red food squares and grow the snake while avoiding collisions with the walls and its own body.
- When the game ends, an alert will appear showing the final score, and then the game will restart automatically.
Please note that this is a simplified example of a Snake game, and you can customize and enhance it further based on your requirements and preferences.
