Sure! Here's a simple game called "Soda vs Milk" implemented in a single HTML file using JavaScript. It is designed for smartphone operation and uses pictograms.
Soda vs Milk
In this game, you can tap on either the soda or milk pictures to attack your chosen enemy. If you successfully hit the enemy, the score for soda increases, and the game declares soda as the winner. However, if you miss the attack, the score for milk increases, and the game declares the enemy as the winner. The opacity of the images represents the current score ratio.
Please note that in the script, I assumed there are two image files named "emozi_rabbit.png" and "emozi_apple.png" which you can replace with appropriate pictograms for soda and milk.
