What an incredible creative construction! On a first glance it looks like unsolvable, but then it reveals its clean solvingpath due to the wisely chosen killer cages and where they are placed. Also I liked the ending- even there a bifurcation was avoided. Mindblowing!

Thanks! I'm glad you enjoyed solving it! This puzzle idea was what got me started designing puzzles and I spent upwards of 100 hours arriving at this puzzle. Definitely no bifurcation needed, but some scratch paper might be handy!

Had abandoned this halfway a few months ago. Came back to it today and I guess the persistence paid off! Very tough, and very creative logic. Needs proper analysis of the various possible combinations in different boxes. On the whole, a fun ride that remains challenging till the very end. Definitely a 5*, at least for me. Thanks, @ bodemeister :).

Hi Bankey, thank you for your comment! I'm super happy you came back to finish it. Everything you wrote is spot on. You are correct it is a 5-star difficulty puzzle. I will change it now.
