Sure, I can provide you with a simple game that meets your requirements. Please find the example code below:

In this example, the game involves controlling a character that moves horizontally on a scrolling background. The player can control the character's movement by pressing the left and right arrow keys. The background continuously scrolls horizontally, giving the illusion of movement. To play the game, you will need to replace the placeholder image file names (`emozi_all/play.png` and `emozi_apple.png`) in the code with actual image files. The background image should be the desired background for the game, and the character image should be a pictogram representing the character. Note: To keep the code concise and within a single HTML file, I have used placeholder images. You can replace them with your own images or use appropriate pictograms as per your preference.
