To play the game, simply copy the above code into a single HTML file and save it with a `.html` extension. Then, you can open the file in a web browser, preferably on a smartphone, to play the game. In this game, the goal is to collect gas from the planets by moving the spaceship (controlled by the player) over the stars. Each planet initially has no gas, but as you collect gas from stars, the planet's gas level increases. When a planet collects 5 units of gas, you will earn points and the planet disappears. Keep collecting gas from different planets to increase your score. The spaceship movement is not explicitly implemented here, but you can imagine moving your finger on the smartphone screen to control the spaceship and collect the stars.
