The puzzle for opening the locker and the 3D text on the table were the two most fascinating things for me. I had never seen them before and they opened my perspectives on what else is possible. I went on to implement these later in my games as well. Also the puzzle required an additional level of technical skills and thank you for sharing that with us in class, along with how to implement the in-game floating text as instructions. It made the play experience so much smoother.
