Thank you for solving the puzzle^^
I love the magic of setting smaller puzzles that’s both having a logical identity and have a strong visual presentation. I like this one in particular, as the pink swirl looks compelling and at the same time has a reason to be shaped the way it is. Not all ideas can be combined like this and most must be scrapped. But when everything fits, like in this puzzle, it’s the best feeling there is, no matter the difficulty!

Once I finished my orientation minute and startet pencilmarking, it took about 30 seconds. Nice puzzle.

The first time i solved it I kinda did it the hard way. Took about 5 minutes. Once i figured what the renban lines meant for the solution i went back and did it again in less than 2 minutes. ;)
