Loved it, had just the right amount of complexity to offer a challenge at the beginning, but breaks down quickly afterwards. Very nice :)

Lovely intuitive break-in. Perhaps I was lucky that it seemed very sensible to me but a definite 2* for me, and I'm not very smart usually.

Maybe I have missed sth, but 3* for me with a quite tough break-in which felt a bit brute-forced due the very deep logic.

Two stars? i really must have missed something very obvious…

Very nice. The start was tricky but once box 3 was sorted out the rest of the solve was facile.

Pretty tough break-in, but once one has the gist of the two boxes you obviously have to start with, the rest falls apart pretty easily. So I think it's maybe more a four star in the beginning and a 1-2 star for the rest.
