Sure! Here's an example of a playable game where you control a dig and climb a tree using pictograms. The game is implemented as a single HTML file, enclosed in script tags, and written in JavaScript.
Please note that you'll need to have `emozi_bear.png` and `emozi_all/tree.png` images in the same directory as the HTML file for the pictograms to show. Also, this game is playable by pressing the up arrow key on a keyboard, but you can modify the controls to suit smartphone operation if needed.
