Sure! Here's an example of a simple game implemented as a single HTML file, using JavaScript and smartphone-friendly pictograms:
Click the balls to score!
10
In this game, the goal is to click on the ball to score points before the counter reaches zero.
When the game is loaded, there will be ten balls displayed on the screen. Each time the player clicks on a ball, the score increases by one and the counter decreases by one. Once the counter reaches zero, the game ends, and the final score is displayed.
Each time the player clicks on a ball, a sound is played, and the ball animates briefly to provide a satisfying visual feedback.
Please note that the sound file "sound.mp3" should be placed in the same directory as the HTML file for the audio to work properly.
