Sure! Here's an example of a simple game where you can play as a character being chased by zombies. The game is designed to run on a smartphone and uses pictograms for visuals. It's implemented as a single HTML file enclosed in script tags:
In this game, you control a blue player square using touch input on your smartphone. The objective is to avoid colliding with green zombie squares. The game will continuously spawn new zombies as long as you haven't collided with any of them. If a collision occurs, an alert will be shown with the message "Game Over".
