Sure! Here's a simple AI physics fighting game called "Roman Shield" implemented as a single HTML file:

To play the game, open this HTML file in a web browser on your smartphone. You can control the player shield's movement using the up and down arrow keys on your keyboard or by tapping/clicking on the game canvas on your smartphone. The objective is to prevent the ball from getting past your shield while trying to score points by getting the ball past the AI's shield. The scores are displayed at the top of the canvas. Have fun playing "Roman Shield"!
