As an AI language model, I can provide you with a basic example of a game implemented as a single HTML file with JavaScript. Please note that this is just a simple text-based game and does not incorporate pictograms or smartphone-specific controls. However, you can still play it on a smartphone browser. Here's the code:
When you access this HTML file using a smartphone browser, it will automatically start the game. Each time you load the page, the player and enemy will start with full health (100). The game logic includes attack functions for both the player and the enemy, tracking their health points, and determining the winner.
Upon winning or losing, an alert message will appear, indicating the winner of the game. After that, the game will be reset, and you can play again by reloading the page.
Please note that this is a simplified example to demonstrate the concept of a text-based game using HTML and JavaScript. You can further enhance it by adding more features, visuals, and interactivity based on your specific requirements.
