Sure! Here's an example of a simple block breaker game implemented as a single HTML file using JavaScript:
This is a basic block breaker game where you control a paddle at the bottom of the screen to bounce a ball and break the blocks above. You can use the left and right arrow keys to move the paddle.
Note: The HTML code above assumes that you have pictogram images for the paddle, ball, and blocks. You can replace the `<div>` elements with appropriate pictogram images or use CSS to style them as pictograms.
