Initially I could not find a way to check if the player input was a password guess (it kept leading me back to an incorrect menu item selection screen) so I hit a wall at that point. Then started looking at what other students had put together before looking at the solution in the video. I still have not looked at the solution, I wanted to post up my own solution before I move on. I leaned pretty heavily on @HeathClose’s solution, I liked how clean it was and it helped me understand how the code structure worked.
For my own solution I added on some more game state variables (level-specific messages and hints) to make the UI a little easier to customize with various menu selections. I tried to label everything as well as I could in the code more for my sake because I kept on getting lost in what method is activated based on what enum Screen was active. I would like to learn alternatives to using if/else statements though. I tried a switch structure and got some weird errors back…so for time sake decided to go back to if/else for now.
