Script

Sure! Here's an example of a simple game where a rolling spike ball destroys everything it touches. It is implemented as a single HTML file using JavaScript and enclosed in script tags. The game can be played on smartphones.

In this game, a red spike ball is drawn on a canvas element. The `update` function is called repeatedly to update the spike ball's position and check for collisions with the canvas boundaries. Additional collision detection with other game objects can be added to the appropriate section. Please note that this is a basic example and actual game logic and additional features can be implemented as per your requirements.
