This challenge was part of 2019's qualifiers, but should still be completable. If you just want to browse, and don't mind the spoilers, check the bottom of the write-up for the solutions.
We've already breezed through a century of computing, vanquished hard-core puzzles, and overcame our fear of maths. Now, for the last challenge before Pixels Camp, we come full-circle with another image gauntlet. But this time we go… cloak-and-dagger.
This challenge is made of steps: each step contains image clues pointing to its answer. Figure it out and you'll jump to the next step with another set of image clues and so on, until you reach the final step with instructions on what to submit below.
This challenge is for time, you will be ranked by how quickly you finish it.
Steps have hints about the number of non-whitespace characters in the expected spelling of their answers, but some alternate spellings are also allowed due to some characters being handled as whitespace. This may be helpful or confusing, you decide.
Submit your answer using the form below, according to the instructions you get in the final step of this challenge. The quizmaster will look into all the answers periodically, so come back in a while to see if you answered correctly.
