Sure, here's an example of a simple Shinchan game implemented as a single HTML file using JavaScript:
Shinchan Game
This game displays a 3x3 grid where the objective is to click on each cell that contains Shinchan's pictogram ('
👦'). If you click on a cell that already contains Shinchan, the game ends and your score is displayed. You can play the game by opening the HTML file in a web browser (preferably on a smartphone for the best experience).
