That was fun. I actually found two working squares. Had to play through both a bit until I found the correct one. Surely I missed a hint along the way haha
[reply: thank you. Puzzle Patzer, in his YouTube solve, spent a long time with two working squares, too. ]

Absolutely in shock that I was able to complete this in under 30 min. Almost didn't have a go at it as I thought it would be way above my paygrade, and yet when I realized how constrained the magic square would be, it unfolded quickly from there - so much fun!
[Reply: the Magic Square Puzzle’s I’ve posted have all been rated 3 star difficulty. Each have a tough break-in working out how the constraint puts limits on where that magic square center 5 might lie. After that, they are a 1 or 2 star.]
