Please note that the code above is just a basic implementation of the game using HTML canvas and JavaScript, and it assumes the existence of image files named `emozi_all/game.png` and `emozi_all/enemy.png` in the same directory as the HTML file. You will need to replace these image files with actual pictograms or symbols of your choice. Additionally, the touch events (touchDown, touchUp, and touchMove) need to be implemented to handle touch input on smartphones.
