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!
17 tries already & I am only sure about the first 5 steps *o* Great level ! Will keep trying. Edit: some years later, finally came to 16 off, then 10, then closer & closer. Sooo many possibilities really make a GREAT level! 65 tries, 4 me, all together. :) And World complete, now. :D
