This constricted maze of pathways is more obvious because of the way the map works. If you didn’t see that you might be fooled that things are a bit more open and expansive. But I’m not sure what the answer is as the map is very useful the way it is for showing where you can explore. Let’s just hope there are fewer of these ‘corridors’ in later parts of the game. I expect that the city itself would be really tight, but that makes sense. I also hope that it’s much bigger than Arx!
