Quite wonderful how this works out at the end with such restriction! I especially liked that opening there, then one spot took me embarrassingly long to spot but it's still worthwhile at the end x)

Finally found the time to solve this puzzle! I enjoyed it a lot. So I'm glad for the inspiration I could provide with my puzzles.
I have to admit I was a bit skeptical about how much the special rule can do as it affects only less than half of the grid. But you used the rule in a very beautiful way!

Thank you Mad-Tyas for solving the puzzle! I am glad I could return some of the enjoyment that I found in your puzzles. I had never before seen fully symmetrical grids, and I enjoy the concept so much, both solving and setting! I btw shared your initial skepticism, but the possibilities appeared to be surprisingly ample :)
