Definitely hard, but the logic is nice and clean. I never had to bog down into full penciling or bifurcating. It is just pretty hard to spot the right places to put pressure on.
Very cool puzzle, really shows the depth 'basic' constraints still have.

+1 to Qodec. A classic oldtimer.

Incredible.
These are so hard to put together because there's never enough room for another clue. And yet, here we have so much juicy immersive logic crammed together into tight spaces that it makes you forget about how rare this type of puzzle actually is. Very impressed.

Very nice but hard - 90 minutes for me!
