Sure, here's an example of an airplane game implemented as a single HTML file using JavaScript and enclosed in script tags:
In this game, the player controls an airplane using touch events on a mobile device. The airplane is represented by a pictogram image. You can replace the `emozi_all/game.png` with any airplane pictogram you prefer. Other game elements such as obstacles and enemies can also be added within the `draw()` function.
Please note that for higher graphics quality, additional assets and images, as well as more complex rendering techniques, may be required. This is a basic example to demonstrate the implementation of a game using HTML, JavaScript, and pictogram images.
