Sure, here's an example of a simple game implemented in a single HTML file using JavaScript, enclosed in script tags. The game is a tapping game where you need to tap on pictograms as they appear on the screen. Please note that the ASMR Tapping aspect cannot be implemented in this text-based format, but you can imagine the tapping sounds while playing the game.
To play the game, simply open the HTML file in a web browser, preferably on a smartphone. The game will display a randomly chosen pictogram every second, and you need to tap on them as quickly as possible. After 10 seconds, the game will end and display your score.
