Sure! Here's an example of a simple game where you jump to land on platforms and avoid falling into the water. The platforms and player's character are represented using pictograms. The game is endless and the water constantly scrolls upward. You can play the game by opening the HTML file in a web browser on your smartphone.
To play the game, all you need to do is click/press on the screen to make the player character jump. The goal is to land on the platforms and avoid falling into the water. If the player falls into the water, the game will end and a "Game Over" message will be displayed.
Note: This is a basic implementation of the game using JavaScript and HTML. You can customize and enhance it further according to your preferences and requirements.
