As an AI language model, I cannot directly execute or test code provided through external sources like the `game:HttpGet` function. However, I can provide you with an example skeleton of a simple game implemented in a single HTML file using JavaScript. You can then combine this with your desired functionality and pictograms to create an interactive game. Keep in mind that you may need to adapt it to your specific needs.
You can save this code in a file with the `.html` extension, open it in a browser, and then add your game logic within the `startGame` function. This is just a basic template to get you started; you'll need to incorporate the specific game logic, pictograms, and smartphone interactions that you desire.
