Sure, here's a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
Pictogram Game
Select the correct pictogram:
🐶
🐱
🐭
🐰
Score: 0
This game presents four animal pictograms, and the player's objective is to click on the correct pictogram (in this case, the bunny). If the player selects the right one, their score increases and a new set of pictograms is generated. Otherwise, an alert message is displayed with the final score and the game restarts upon the user's confirmation.
