Very nice logic on this one. A nice break in and a smooth flow overall. On the top half of 2 stars for me.

Superb puzzle, a wonderful showcase of the entropic lines constraint.

Loved that. Thanks!
The break-in and first steps were 3 stars difficulty for me, from there on more on the 2 star side.

Very nice! Loved how the flow wasn't interrupted, and could always see some logic without thinking many steps ahead.
