For example, I wrote that when playing through "007 chases Dr No," Bond did not receive air magic, and without it, he couldn't reach the Necropolis of Dusternis, where the Purple hero Isra was holed up, and therefore the playthrough couldn't be completed. So, (for the first time ever) I used the Admiral's Hat Bug: I couldn't just start the whole thing over!
It might not seem fair, but in this situation, it was a necessary measure, because the author tried to put the player in a situation where he had to figure out for himself what he needed to win. Now, of course, it's easier because there's the Internet, discussions on forums, and even video walkthroughs. But once, players were "one-on-one" with the Author's Design.
