Script

Sure! Here's a simple space-themed game that you can play by creating, collecting gas, and having fun with planets and stars. Since it's a program, you can copy and run it in a single HTML file enclosed in script tags. Let's get started:

To play the game, simply copy the above code into an HTML file, save it with a `.html` extension, and open it in a web browser (preferably on a smartphone for optimal viewing). You'll see a canvas element representing the game area. Tap or click on the planets to collect gas and increase your score. The gas count on each planet will be displayed, along with the overall score. The game loop continuously redraws the canvas to update the positions of planets, stars, and the score. The gas count is incremented whenever you click on a planet. The game also includes two stars, represented by yellow circles, for visual variety. Feel free to customize the game further by adding more planets, stars, or implementing additional features.
