As an AI language model, I can provide you with a simple example of a game implemented as a single HTML file using JavaScript. Keep in mind that this is just a basic example and does not include advanced features like GTA, infinite bullet guns, or high-quality graphics. Additionally, since this game assumes smartphone operation and pictograms, it will be a text-based game rather than a graphical one. Here's the code:
In this example, the game starts by calling the `gameLoop()` function, which continues executing until certain conditions are met. The `shoot()` function simulates shooting a target, deducting a bullet from the player's ammo count, and increasing their score. The `displayStatus()` function shows the current ammo count and score in the console. You can expand this code to include additional game mechanics and pictogram-based interfaces.
