Sure! Here's an example of a game that allows you to design starships for cruise lines using JavaScript in a single HTML file, enclosed in script tags:
Starship Designer - Cruise Lines Edition
Select Ship Components:
In this game, you can select different components (represented by pictograms) from the component container and double-click on the ship's container to add them to the ship. Each component has a specific image and data-component attribute to identify them. The selected component has a blue border. You can modify the game design and replace the existing pictograms (cabin.png, pool.png, restaurant.png, and spa.png) with your own according to your preferences.
Please note that this is a simple example and you can expand upon it by adding more features, such as ship customization options, saving and loading ship designs, and so on.
