Build me a polished Bible learning game that works offline and saves progress in the browser, so people can open it and start playing right away with no account or install needed.

It should cover the whole Bible across all 66 books, with a big question bank, multiple difficulty levels, and several ways to play, like quick rounds, guided journey stages, adaptive review for weak areas, collections, and a two player duel mode. I want it to feel like a real learning app, not just trivia, with clear feedback after answers, Bible references, memory hints, and explanations for wrong choices.

Make it responsive for desktop and mobile, support light and dark themes, keyboard and touch controls, and be easy to pick up and continue later. If you need current implementation details, look up the latest docs online and make sure the final result feels complete and ready to publish.
