Frankly, the only time I felt there was insufficient information was in the immaculate trials, with the four weighted switches. Otherwise, I think it's pretty well done so far (albeit, I'm only in Heiberheim right now, still looking for the 'WW')
I just did this yesterday and it just increased my appreciation of the game.
It took me a good 15min or so to figure it out and once I solved it, it felt really good because it had all the necessary clues but wasnt overly easy, and best of all was the feeling of solving it without help from google.
However I can understand that many would get frustrated with it. Especially since it's a puzzle that you cant leave and come back to later. There have been some puzzles that I havent been able to figure out so I've had to just leave them be and come back later.
The game has a lot of problems and bad design choices, but amongst all things these puzzles have been one of the things I'm enjoying the most.
