Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript:
Click the target as fast as you can!
Score: 0
Time left: 10 seconds
In this game, the player's goal is to click on the target (represented by a pictogram image) as fast as possible within a given time (10 seconds in this example). The player's score is displayed, and the timer counts down the remaining time. The game ends when the timer reaches 0, and an alert shows the player's final score.
Please note that you would need to replace `"emozi_all/pictogram.png"` with the actual path to your desired pictogram image.
