I remembered that GZdoom has options to make the map more useful. I customized my experience and I'm having a splendid time
* Normal height changes/doors are dark green
* Locked doors show up as the color they are
* Teleporters are light green
* Level exit is orange
* Secret areas are pink
* My location is a custom arrow that lets me see which direction I'm facing https://github.com/mmaulwurff/zdoom-arrows
