(puzzle spoilers)
@dodec Honestly, I blew it but I think it's pretty solid. I was SO CLOSE, just let myself get discouraged when the word lengths didn't quite match up with the numbers. I also failed to notice the extra gems, so this is DEFINITELY a failure of my own follow-through and not of the puzzle. I think it's just about right, well-hinted and follows a relatively common puzzle style. Being off by one felt like a bit big of a monkey wrench for novice puzzlers, but for engineers... yeah, feels just about right. I look forward to seeing more of these.
