"Lost and overwhelmed" is pretty much how I'd describe how I felt during the whole area, to be sure. I feel like it would've been better handled as a 'storybook' sequence like in Pathfinder: Wrath of the Righteous, where a sequence of skill checks and player choices let us navigate the situation without having to struggle with clumsy controls and fiddly pathfinding in such a life-or-death race against time. I get so frustrated and angry just trying to figure out what's going on and where the triggers are that will cause scripted events to progress, it takes me right out of the narrative and reminds me I'm playing a video game, and a broken-feeling one at that.
