Sure! Here's an example of a simple jumping game where the character is a police officer chasing a criminal by jumping up a building. The game is implemented as a single HTML file, enclosed in script tags, and written in JavaScript. It can be played on a smartphone.
To play the game, you need to open the HTML file on your smartphone's browser. The game will start, and you can tap on the screen to make the police jump. The goal is to catch the criminal by jumping on top of him. The game will display a "Game Over" message if you catch the criminal or if the jump takes too long.
