It still wasn't particularly engaging though, but a purely mechanical exercise in pencilmarking and ticking off the obvious conflicts. It's answering the question of "could you have an irregular layout" rather than "what kind of interesting puzzles can you design only with an irregular layout". There was not a single "oh, wait, this ruleset actually also implies X" deductive leap, no place where it felt like there was some cool emergent property of the ruleset.
