Mazescape 2018

This is the third Unity C# game I have made and I am still learning.  I made this game to teach / quiz my Chinese students on their C# learning.  When a door is clicked, one of eleven C# questions is displayed and the door will only open if the answer is correct. 

If you wish to turn off the C# questions and simply navigate the maze, the cheat code is pressing N key and the M key together.  Also to open the mini map, press the Z key and the M key together.

Advice is welcome.
