I was lead here by a puzzle called "Black Hole" and its reviews.
I just demoted this to Professor. If not for that, this would've been my first Grandmaster!
Obviously very, very broken. I didn't find the final path quite as interesting as previous reviews indicated, but it was a pretty enjoyable optimization process nonetheless.
While it's undeniably broken, the resulting path is so unorthodox that even finding your way to the exit is a challenge in itself. And then we also have a very unintuitive 2 off trick as well!
