Very tightly designed both puzzle-wise and visually. Quite enjoyable. There are so many 71s, took me a long time to spot the 69. Nice puzzle Went from 73 to 69 so I missed all the cool 71s rip Loved it!
Had 71s, for quite a while. :) Cool! Took me a while to get past 71 Enjoyed, but unsure what I am missing on the high ratings. Solution wasn't too difficult to discover for me. I also got 2 off initially. But my problem is that I tried to pipeline when it is not needed. LOL.
