Sure, here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
In this game, you control the "Brooklyn 99" pictogram using the arrow keys on your smartphone. The objective is to avoid colliding with the enemy pictogram. When a collision occurs, the game ends and you are shown your final score.
Please note that you need to have `emozi_himawari.png` image file in the same directory as this HTML file for the pictogram to be displayed. Feel free to replace it with any other relevant pictograms you have.
