Script

Sure! Here's an example of a game implemented as a single HTML file, using JavaScript and enclosed in script tags. The game involves a rolling spike ball destroying everything on its path, while squares continuously spawn on the screen. This example assumes smartphone operation and uses pictograms for visual representation:

In this game, a red spike ball rolls from left to right and back, destroying green squares that continuously spawn on the screen. The spike ball can change direction when it reaches the edges of the game area. The game updates every 10 milliseconds. Please note that this is a simplified example and can be further enhanced with additional features, levels, scoring, and more.
