Sure! Here's a sample game called "Ninja Flip Game" implemented as a single HTML file, using JavaScript and enclosed in script tags:

In this game, you control a ninja character using the arrow keys on your smartphone. The objective is to move the ninja around the canvas while avoiding any obstacles or enemies that you can add to the game later. This sample provides the basic structure for the game, with a moving ninja character, score display, and keyboard event listeners. Feel free to customize and expand this game by adding more gameplay features, levels, or graphics as per your requirements.
