Ich war an manchen Stellen zu voreilig... - tricky.

I am afraid that some players might have used bifurcation instead of searching for the logic path, and because of that gave a lower rating.

Had to be pretty clever with some of my eliminations on this one. After quickly filling in my first 2 numbers, the rest of it slowed to a crawl, with steady but slow progress.
Once I finally started that chain reaction to fill in the entire puzzle, I was worried - it felt so suspicious that things were moving so smoothly for so long!

A bit more finicky than the other I've, but also fun!
