I asked in Discord and someone else mentioned the circled area seems obsolete. I'm going to figure out how to properly incorporate that room. The bottom path has some problems that I'll need to address that could make the pink path more useful as a rotation.
Question though: The pink square corridor is an open atrium with a sight line through the middle. Knowing this, do you still think it's too convoluted? The players have pretty clear vision through the area, but have to make lots of different turns. Should I worry about that?
