I built a daily regex game. Scoring regex fairly was the hard part

I like regex golf: the challenge of writing the shortest pattern that does a job. So I built a daily game around it, Regex Hunter. Every day there's one hunt, the same for everyone. You get a few words to catch and a few to spare, and you write one pattern that matches every target and none of the decoys. Then you try to make it shorter, against a par.
