Sure! Here's an example of a simple dress-up game written in a single HTML file using JavaScript and enclosed in script tags. This game allows you to dress up a character using pictograms. Keep in mind that this is a basic implementation and can be further enhanced with more features and styling.

To play the game, simply run the HTML file in a web browser. It will display a character represented by the ☠️ pictogram. By clicking on different pictograms below the character, you can change its appearance. You can customize the available pictograms by adding more options using their respective Unicode representations.
Note that this is a very basic dress-up game, and you can expand upon it by adding more functionality, such as different clothing options, saving and sharing outfits, etc.
