Please note that this is just a framework to get you started. You'll need to implement the actual game mechanics, graphics, and user interface to create a playable game. You can replace the console logs with the actual game logic and update the HTML and CSS to display appropriate pictograms.
Feel free to modify and expand upon this code to create an enjoyable Mega Man game for smartphones or other devices. Remember that this is just a starting point, and you'll need to add more code to make it a complete game.
