3D Game User Interface Design

What is the project about? We are creating a 3D educational game for students aged 7-12 years old. It touches on the subject of Social Studies. The game primarily involves a character walking around an open world triggering conversations and quests, collecting items and answering simple questions while learning more about the topic. What we need? We will be needing the user interface design for the game. This would includes the main menu, lesson selection, login and registration page, in-game HUD, mini-map design, activities (drag and drop, text MCQ, image MCQ, Fill in the blanks, information display), conversation box and icons. We will be providing the wireframes to understand what would be required for each scene. However, we would need a proposed design direction (2-3 samples), after we choose the preferred style you can proceed with all the scenes for the design. At the end of the project, we would need the working files (AI/PSD) arranged with the scenes and a collection of the UI Elements used.
