Can you access the open-air portions from the Entry Way (Area 1)?
In the intro to Dungeon Level 1, it says:
"Enterprising adventurers might realize they can clamber up the walls of the open-air portions ... The following rooms can be exited and entered in this manner: 13, 18, 19, 42, and 61"
My PCs have discovered this feature, climbing up from Room 13. I showed them the awesome colour picture (on p.48-49), and it appears to show the Entry Way as well as the aforementioned rooms.
Just curious about what the intent was; in my game you can't climb up from the Entry.
