That was a very fun solve. Flowed really smoothly after the initial break-in (9:52).
I really liked this solve. Like Menderbug said, it flowed really nicely after identifying the starting constraint. Thanks!
Checked the solution video of this puzzle and then solved the puzzle. Really a nice puzzle.
