Kumiko7/visual-novel-gemini-generator — reverse-engineered prompt

Build me a simple browser app that can live generate a visual novel using Gemini. I want to give it a story idea, genre, characters, setting, and maybe a tone or mood, then have it create the novel scene by scene with dialogue, narration, character art, background images, and matching music. It should feel like an actual playable visual novel, so I can read through scenes, make choices if that fits, and watch the story continue as new text, visuals, and audio are generated.

Please make the interface easy for a normal person to use, with a place to enter the prompt, start generation, and move through the novel as it is created. If possible, keep the generated assets organized per scene and make it clear what is still loading. It should run locally with a Gemini API key in an env file. If anything is unclear, check current Gemini docs online and make sensible choices that match this project.
