Sure! Here's a sample game implemented as a single HTML file, using JavaScript and enclosed in script tags. The game is designed for smartphone operation and is text-based rather than using pictograms. You can copy and paste the code into an HTML file and open it in a web browser to play the game.
In this game, you have a score and a number of lives displayed on the screen. You can increment the score by tapping the "+" button and decrement the lives by tapping the "-" button. If your lives reach 0, the game is over and you can restart it by tapping the "Restart" button.
