Sure! Here's an example of a simple game with right and left controls where the background scrolls when you press the corresponding button. Since you requested the use of pictograms, I'll use some simple arrow symbols for the controls. Just copy the entire code below and save it with a ".html" extension to play it as a finished game in any modern web browser.
In this game, you'll need to replace the `background.jpg` and `emozi_all/game.png` URLs with your own image files for the background and player character. The background will scroll horizontally as you press the left or right arrows, and the player will move accordingly. Let me know if you have any questions or if there's anything else I can help you with!
