Sure, here's an example of a simple game implemented as a single HTML file using JavaScript:
Pictogram Game
Score: 0
This game is a simple click-based game where the player needs to click on the pictograms to increase their score. Pictograms are represented as images, and each time a pictogram is clicked, the score increases by 1. The current score is displayed at the top of the game. Feel free to replace the pictogram image URLs with your own pictograms. Have fun playing!
