I think this is a bit more than a 2-star difficulty... unless I'm missing something!!

Good puzzle. Need to play around with the tail area to move forward. Once that is figured out, the rest falls into place.

Challenging, but nice image and one unique solution. Thank you for the puzzle.

'Only' a silhouette but very enjoyable.

Thank You.

Superb puzzle. many thanks.

Very tricky, but very good.
