Sure! Here's a simple game implemented as a single HTML file using JavaScript:
Pictogram Game
Score: 0
This game will display a random pictogram (emoji) and the player needs to click on it. If the clicked pictogram matches the current pictogram, the score increases and the next pictogram is shown. If the clicked pictogram doesn't match, the game ends and it displays "Game Over!". The player's score is shown at the top.
