Sure, I can help you create a simple game implemented as a single HTML file, using JavaScript and enclosed in script tags. Keep in mind that this implementation is a basic example and may not have all the functionalities you desire. Also, note that Cozmo robot integration is beyond the capabilities of a single HTML file.
Here's an example of a game where you can interact with pictograms on a smartphone:
Pictogram Game
In this example, there is a game screen with four pictograms displayed. Each pictogram image has a class of "pictogram". When a pictogram is clicked, the event listener attached to it triggers, and you can perform any desired action inside the event handler (currently logging a message to the console).
To use this, you would need to replace the `src` attribute of the `img` tags with the URLs or paths to your own pictogram images.
Keep in mind that this is just a basic implementation to get you started. You can add more game logic, scoring system, levels, etc., based on your requirements.
