I bought the physical copy of this the other day and I really like it!
There appears to be a little mistake I think: in area 22 there is a tomte carrying the ring to area 4? Which gate does this refer to? There is no gate at area 4. I assume you mean key to area 24??
Also the tunnel from 23 leads to 29? Shouldn't it be leading to 30?
Is there an Errata for the physical copy, for maybe I overhead other mistakes?
But overall a really nice adventure, I might like to run it some day!
