The feedback has been the break in for this puzzle is quite challenging, and I do like to do solve videos for my puzzles in case people get stuck and would like some help.

Very nice! I didn't find the break in too difficult but I used some minor bifurcating. Definitly gonna watch your video to see the intended break in.
BremSter: I have no problem with however you solve the puzzle. I hope you find the intended break in interesting.
