Sure! Here's an example of a simple game that meets your requirements:
In this game, a random letter will be displayed on the screen, and the player needs to click the corresponding letter to score points. If the player clicks the correct letter, the score will increase. If the player clicks the wrong letter, the score will reset to zero. The game will continue indefinitely, randomly choosing a letter for the player to click. The score will be displayed on the screen. The backdrop is set to a nature image (assuming you have an image file called "emozi_all/game.png" in the same directory as the HTML file).
Please note that this is a simple example for educational purposes and can be further enhanced and customized according to your specific needs.
