As an AI text-based model, I am unable to directly create or implement HTML files. However, I can provide you with a simplified example of how you could structure a game concept using JavaScript within an HTML file. Please note that this is just a basic example and should be expanded upon to create a fully functioning game. Also, keep in mind that creating complex games often requires additional frameworks and libraries.
In the provided example, we have a basic HTML structure with a game container to hold the game elements (represented by `div#game-container`). You can use `<img>` tags with appropriate `src` values to display pictograms or images of players, obstacles, enemies, etc. Also, make sure to add any necessary CSS styles to customize the appearance of your game.
Within the enclosed `
` tags, you can implement the game logic using JavaScript. The `window.onload` function ensures that the game script executes when the page finishes loading. You can handle user input events (e.g. touch events for smartphones) to control the game elements, update the game state, and redraw the elements within the game loop (`gameLoop`).
Keep in mind that this is a very simplified example, and depending on the complexity of your desired game, you may need to implement additional features, use external libraries or frameworks to handle graphics, physics, etc.
