Yesterday was officially the first day I failed to complete the puzzle on the day, due to a busy schedule. I'm still planning on getting caught up and saving Christmas, but now I've got a bit of a hill climb. How caught up are you?

The Puzzle

In today’s puzzle, the elves have cooked up some sort of graph-based regular expression tree, and they need help parsing through it to get messages from their satellite in order to get pictures of a sea monster! These elves sure do spend a lot of time coming up with their own custom interfaces and protocols.

The Leaderboards

As always, this is the spot where I’ll plug any leaderboard codes shared from the community.

Ryan's Leaderboard: 224198-25048a19

If you want to generate your own leaderboard and signal boost it a little bit, send it to me either in a DEV message or in a comment on one of these posts and I'll add it to the list above.
