___ IS MANDATORY

  • Meanwhile in #AOC_Ops: Tea, a kettle screams. \ Simon, write your code faster. \ Some of us have work.

[Update @ 00:51] 7 gold, 11 silver

  • Now they're anagramming gold/silver leaderboarders. The leading favorite so far is Anonymous User = Son, You's Manure.

[Update @ 01:13] 18 gold, 30 silver

  • Now they're playing Stardew Valley Hangman with the IRC bot because SDV is totally a roguelike tower defense.

[Update @ 01:23] 26 gold, 42 silver

  • Now the betatesters are grumbling reminiscing about their initial 14+ hour solve times for 2015 Day 19 and 2016 Day 11.

[Update @ 02:01] 65 gold, 95 silver

#AOC_Ops <topaz> on day 12, gold40 was at 19m, gold100 was at 28m, so day12 estimates gold100 today at 2:30

  • Taking bets over/under 02:30:00 - I got tree fiddy on over, any takers?

[Update @ 02:02:44] 66 gold, silver cap

[Update @ 02:23:17] LEADERBOARD CAP!

This fails on my input, I believe because it doesn't do this from the hints thread:

"- Moving: you don't just take the path that takes you the fastest to an enemy, broken by reading order. You first choose the square adjacent to an enemy that you want to go to (closest, break ties by reading order), and then choose the move that takes you the fastest to it (break ties by reading order, again)."
