Sure, I can create a game for you using JavaScript within a single HTML file. Here's an example implementation for a simple guessing game:
Guess the Pictogram!
In this game, you'll see a random pictogram displayed on the screen, and you need to enter your guess in the input field provided. When you click the "Submit" button, the game will check if your guess matches the chosen pictogram and display a corresponding message. Feel free to customize the pictograms array with your own choices and add more styling if desired.
