At a guess, this was meant to be on the easy end of "easy". Certainly being essentially out of practice for the better part of two years but being able to complete within three hours when one of the limiting factors was how fiddly it was to draw letters freehand in Paint suggests that. On the other hand, ruthrobin was kind enough to send last week's Listener as another one to sink my returning teeth into, and I took one look at it and thought: "Nah. Too much like hard work."
So perfect to bring new solvers, or absent ones, back to the fold. Perhaps if I had encountered this in the heady days of 2014/15 when I was attempting maybe 150 such puzzles a year, it would have been less special and I might privately be repeating Alekhine's moan, the only real gimmick being the grid layout, but from where I'm sitting it's a perfect puzzle to get started again.
So there's that to consider as well.
