Sure, here is a basic implementation of a gun builder game using JavaScript within a single HTML file:
Gun Builder
Build your own gun:
Your Gun:
In this game, there are six gun parts represented by pictograms. When a part is clicked, it gets added to the `selectedParts` array and displayed under the "Your Gun" section in text format. This allows the player to build their own gun by selecting different parts.
Please note that this is a very basic implementation and can be expanded upon with more features, customization options, and interactivity based on your specific requirements.
