Sure! Here's a simple game called "Watermelon Popper" implemented as a single HTML file with JavaScript. It can be played on a smartphone and uses pictograms.
Watermelon Popper
This HTML file sets up a basic game interface for "Watermelon Popper". When the watermelon image is clicked, the score is increased by 1, and the updated score is displayed.
To make the game fully functional, you would need to add additional features like a timer, game over condition, and visual effects. You can also replace the "emozi_all/game.png" file with a suitable pictogram or image. Feel free to customize and enhance the game to your liking!
