Sure! Here's a simple game implemented as a single HTML file, using JavaScript and enclosed in script tags. The game is based on the popular character Sonic the Hedgehog, and you can control Sonic using smartphone operations such as tapping or swiping.
Please note that in the above code, I used a placeholder `emozi_himawari.png` to represent the Sonic pictogram. You can replace it with an actual image of Sonic to enhance the game visuals.
