Teenage Quiz Learning Game -- 2

I’m developing an educational game aimed squarely at teenagers that turns the usual study session into a fast-paced quiz challenge. Players will move through timed rounds of multiple-choice and short-answer questions that span Math, Science, and History, with difficulty scaling as they progress.

Here’s what I need from you:
• A complete game loop that supports quiz and test mechanics, including question banks, scoring, streak bonuses, and instant feedback.
• A clean, intuitive interface that appeals to a teenage audience (mobile-first but responsive for tablets and desktops).
• Robust content management so I can add or edit questions in each subject without touching the core code.
• Lightweight analytics hooks to track topic mastery and session length.

Unity, Godot, or another cross-platform engine is fine as long as we can export to iOS, Android, and web. Code should be well-commented, asset-ready, and tested for smooth performance on mid-range devices.

I’ll consider the project complete when I can:
1. Install the build on a phone, open any subject, and play ten flawless quiz rounds.
2. Add a new set of Math questions via a spreadsheet or JSON file and see them live in-game without recompiling.

If this sounds like a challenge you’d enjoy, let’s talk schedule and milestones.
