Sure! Here's an example of a simple game called "Normal Kombat 1" implemented as a single HTML file. It uses JavaScript and is enclosed in script tags. The game can be played on a smartphone and utilizes pictograms for visuals. Please note that this is a basic implementation to give you an idea of how it can be done.
Please note that this is just a starting point, and you'll need to add more game logic, styling, and interactivity based on your specific requirements.
