Script

Sure! Here is an example of a simple space runner game implemented as a single HTML file with JavaScript code enclosed in script tags. It can be played on a smartphone and uses pictograms to represent objects in the game:

This code sets up a simple space runner game where the player controls a spaceship using the "jump" action on a smartphone screen. The objective is to avoid the red obstacles scrolling from right to left. The player's score increases by successfully avoiding obstacles, and the game ends if the player collides with an obstacle.
