Sure! Here's a simple game implemented as a single HTML file using JavaScript. The game allows you to move an angle icon, feed a dragon, and watch it evolve and become stronger based on the number of times it is fed.
To play the game:
1. Save the code as an HTML file (e.g., `dragon_game.html`).
2. Open the HTML file in a web browser.
3. Use your smartphone's touch screen to move the angle icon within the game container.
4. Tap on the game container to feed the dragon.
5. Every 3 times you feed the dragon, it will evolve and change its appearance, becoming stronger by adding more fire emojis.
Enjoy playing the dragon feeding game on your smartphone!
