I got to the final stage and assumed there was just one correct answer to each part. I wonder how many other entrants were foiled in this way.
I gave the correct answers to Where, Algebraic, Manifold Agreement, Looter, Graph Theory, Wordsearch, Registration, Crossword and Banner.
However I only entered one answer to each of Sum and Message even though I knew there were other possibilities.
Despite obtaining WHAT_IS_THE_KEYWORD_FOR_THIS_CIPHER I got Cipher wrong by giving the answer as WHAT. I think that was my worst mistake.
