Thanks Matt, that’s very kind. It seems I’ve achieved the difficulty level I’ve been striving for, which is ‘a bit too easy for the 15^2 hardcore’. Hopefully that means it’s the right level for the silent majority!

Haha! Good point about the silent majority - will remember that. I'm still working on that, trying to undo 1. A vague misguided sense that hard=good (or more to the point, easy=weak) and 2. A lack of skill in making clues both approachable and interesting.
