Sure! Here's a simple game that can be played on a smartphone using pictograms. It's implemented as a single HTML file using JavaScript, enclosed in script tags:
Particle Game
In this game, there is a single pictogram representing a particle. The player can touch and drag the particle on the smartphone screen to move it around. The particle will follow the player's finger movement. When the player releases their touch, the particle will stop moving.
Please note that in this example, I assume you have an image file named "emozi_himawari.png" available in the same directory as the HTML file. You can replace "emozi_cat.png" with the actual image file name you have for the particle pictogram.
