Brilliant puzzle! The break-in was quite difficult for me but once found it flowed beautifully.

One of the solutions that I've got. It seems valid. Anyone let me know where's the mistake? Thanks.

A lot of hard-fought logic to solve this one, especially finding the break in. Amazing setting to come up with this.

Wow. Just wow. You just can‘t imagine, that this minimalistic puzzle has a unique solution. And it’s not too difficult to find it. One of my all time favorites.

By “one cell wide” path, does that mean the path can only turn 90 degrees at a time, or can it go up on, say, a diagonal? Like could r3c2 connect only to r2c3 and r4c1, for example?

@nyxie:
The path must be orthogonally connected, so it cannot go up on a diagonal. I'll update the rules to make it clearer soon. Sorry for that!

Incredibly good ! Once you get the opening trick, it solves so fast and easily that it is almost unbelievable with such an empty grid and simple ruleset ! This goes straight to the hall of fame !

Magnificent.

Genius settings!

@spot10: I can assure that this puzzle has a unique solution. Maybe you missed a rule (e.g. that the snake is basically a German Whispers line) or an implication by the rules.

Absolutely incredible puzzle - as can be expected from this cat.
The fact that this has a unique solution was itself very impressive, but the solution path was just marvelous!
Bravo!
