IMPORTANT: Enter all answers in Morse code! Use 0 to represent DOT and 1 to represent DASH. For those of you who don't have Morse code memorized, here's a reference: https://en.wikipedia.org/wiki/Morse_code
I make puzzles (of all different kinds, not just crosswords!) at https://puzzlesforprogress.net. If you liked this puzzle, you might like those!
I knew trying to do this without the reference would backfire. I had the Y wrong in "say" (I entered it with the dot in the wrong spot) and it took some time to fix. BONKERS idea, by the way. (I've been playing Keep Talking and Nobody Explodes recently so most of Morse code is fresh in my memory)
Wow! I'm out of practice with Morse code, so I restarted halfway through, but I'm still proud of myself. I was also thinking of something like this but your execution was just marvelous!
