Sure! Here's a simple game called "Ball Catcher" implemented as a single HTML file with JavaScript. The game assumes smartphone operation and uses pictograms for visual elements.
To make the game work, save the pictograms for the player and ball as `emozi_all/game.png` and `emozi_all/ball.png`, respectively, in the same directory as the HTML file. You can replace these pictograms with your own or use different visual elements.
The game involves catching falling balls by moving the player left and right using touch controls. Each time a ball is caught, the score increases. However, if a ball reaches the bottom without being caught, the game ends and the score resets.
