As an AI text-based model, I can provide you with an example of a simple game implemented as a single HTML file with JavaScript enclosed in script tags. Please note that the below code is for demonstration purposes only and may not include advanced game features or complex logic. Additionally, due to the limitations of text-based models, I am unable to generate pictograms or images. Here's an example:
Simple Game
This example sets up a simple game where you can control a blue square using touch input on a smartphone. The player's square follows your finger's movement on the canvas. You can further enhance this game by adding game mechanics, scoring, and more. Remember to save the code as an HTML file and open it in a web browser to play the game.
