More cramped Ancient Cities

The ancient cities are great, the problem is they feel too open to be as scary. I haven't had a lot of experiences where I felt cramped and stuck near the warden in the cities, however, in caves (especially spaghetti caves) escaping and avoiding the warden feels more challenging and scary because the caves are so cramped and tiny. I know they're supposed to be open cities, but having the feeling of running around makes it feel less terrifying. TL;DR make ancient cities less open to add to the scare factor
