Unity 3D Game Development

Hi, Objective of the project: Build a Game with Virtual reality walkthrough. This game will contain an empty rectangular box with the top lid open. The goal of the game is to allow the user to pick up geometrical shapes and place them in this container. The geometrical shapes come in three different shapes - squares, cubes and spheres. Each shape will be available in 3 different colours - Red, Green, Blue. As part of the output, we require two logins - admin user and normal user, with different functions. An admin user can upload the 3D base models, which include the empty rectangular box. The admin user can also maintain the list of shapes as well, which will also be uploaded as a 3D model. A normal user can fetch the base model in his screen and the list of available shapes on the right bar. The game of selecting, picking up and placing the shapes in the container should be displayed in Virtual Reality with a walk-through around the container. Also would like to see some work which has been already done by you/team. Please share the reference links .
