Tarek,
Thanks for another really great puzzle.

Unfortunately I have gotten a bit behind with both solving and creating puzzles.
Currently trying to catch up.

Thanks Børge,

I have been consumed with work in the past months. All of my submitted puzzles come from a pool of puzzles generated several months ago. I hope that I can dedicate more time in the near future :sun:
