            This application is an interactive storytelling experience where you are the author. Create a unique world, design your character, and let our AI agent weave a narrative tailored to your choices. It's a blend of a game constructor and a visual novel, powered by generative AI.
            
            ## 🎯 Key Features
            - **🤖 AI Game Master**: An intelligent agent that generates a dynamic story with branching narratives based on your inputs.
            - **🎨 World Building**: Define your own game setting, from fantasy realms to sci-fi dystopias.
            - **👤 Character Creation**: Customize your protagonist's name, age, background, and personality.
            - **🎭 Genre Selection**: Choose from a variety of genres to set the tone of your story (e.g., Fantasy, Sci-Fi, Mystery).
            - **🖼️ Visual & Audio Experience**: The AI generates images and background music to accompany the scenes, immersing you in the story.
            - **✍️ Interactive Choices**: Guide the narrative by selecting from AI-generated options or writing your own custom actions.
            
            ## 🛠️ How It Works
            
            1.  **Construct Your World**: Use the forms to describe the setting and your character.
            2.  **Choose a Genre**: Select the style of your adventure.
            3.  **Start the Game**: The AI will generate the opening scene based on your setup.
            4.  **Make Your Choices**: Interact with the story by choosing from a list of actions or writing your own.
            5.  **Experience Your Story**: Watch as the AI dynamically creates a unique story with text and images just for you.
