The idea fits the theme and the menu have a good amount of buttons, but I feel like there could be more features and polishment to further enchance the game itself. To cite a few examples, it would be really cool if the city was crowded and you had your friends following you. Then, there could be some groups of grey people that only become your friend if you already have a certain amount of friends with you. The grey characters could also have a red arrow above them so it would be easier to locate them.
Regardless, you designed and made a fully functioning 3D game (I didn't came across any bugs) in just a week, so nice job!
