Sure, I can create a simple game for you that can be played as a finished game. Here's an example of a game implemented in a single HTML file with JavaScript enclosed in script tags:
This game will create random pictograms (such as cars, rockets, etc.) on the game area at random positions every second. The pictograms will disappear after 2 seconds. The goal of the game can be customized based on your requirements. You can further enhance the game by adding scoring, levels, and additional gameplay mechanics as needed.
