I wonder if there is something under the lava pools in the crypt. And also behind the lava in the wall, by the chains trap in level 2. I don't think there is any treasure (how could you possibly reenter the level and survive?), but knowing Tango, he might have placed a sign with some mocking message 😅
Has any hermit checked those places yet? I know Pearl has mentioned a couple of times that she wanted to check the lava pools, "but not on this run". Still haven't seen her last week runs, waiting on the Youtube movie.
PS. not sure if I should mark this as spoilers or not. Best to err on the safe side, I guess? :)
