When you say ‘manual-check’ do you mean, you have to check the manual to pass the security feature in the game? KQ5 has it where three times in the game you have to look up in the book some spell symbols. Once when you push the boat out to sea and when you try to crowbar the gate at the castle and I think when you scare the snake at the mountain pass. I wish they had made the symbols a little more different from each other. I wonder if it was made the way it is to prevent copying of the manual?
