Like the one where you have to find 4 tiny buttons that perception/alt won't detect, then realize that one of the countless books you picked up along your journey wasn't just spam, unlike the 99.9% of them that were, but in fact held the key to the puzzle.
Then there was that temple where you needed to light the torches, or whatever, in order to enter, even though it should've been possible for you to just telekenisis your pyramid over the chasm. But you couldn't, because there was an invisible wall there.
Big deal? Well, barely a moment after that you're faced with a puzzle that look exactly the same.... except you have to throw your pyramid over and teleport to it, which the game just conditioned you into thinking wouldn't be possible, with its invisible wall in the previous area.
Stuff like that is what made the puzzles bad. You bombard the players with books that are all pointless spam (and not actually interesting to read, with text like 'this book describes the adventures of gooraah the barbarian' fullstop, so you condition your players to not even look at them), then you require them to read a book in order to solve a puzzle. You erect invisible walls to prevent one way of solving a puzzle in one room, then require that you solve the next puzzle in exactly the same way that you established wasn't possible in the previous room.
Never mind the parts where sometimes you remove obstructions by attacking them, other times you remove them by walking through them, other times you remove them with hidden buttons right next to them, other times you remove them with hidden buttons in entirely different rooms, and other times the obstructions are just red herrings... there's no consistency at all. So the "puzzles" just boil down to try everything you can think of in every room you come across and hope that one of them work out purely by chance.
This isn't fun, it's just wasting your time as you mindlessly go through the checklist then move on.
