I liked this hold overall: it was worth a 8 or a 9 in rating (probably 9 because of the architect's comments), and around 6 for difficulty.
Happyhouse put me off at first because of the fairly disorganised layout, with almost all rooms being on one side of the dungeon, instead of being spread more or less evenly (and the 4W rooms). My initial bad impression soon wore off though, and I enjoyed some of the rooms quite a lot: 2N, 1W is among my favourite rooms of the hold, with a very nice "
how a situation can get out of control quickly"
approach. There was no particularly weak rooms, with the notable exception of 2W: I have found the six queens in this room to be too much, as they did not make the room much harder, but they increased the length of the room quite a lot (2W is in the top 20 of the longest rooms at the moment, despite having been solved by StuartK).
Happyhouse is the level where my feelings are the most polarised: many of the ideas are original, but I think some rooms could have used some more polish. For that reason, I'm not sure how I feel exactly about that level.
Impossible Cubes had a strong concept with the 1W, 1N 1W and 2N 1W rooms, very enjoyable rooms to play. I have found some of the other rooms to be somewhat dull however, particularly 3N and 3N 2W; still, they did not make the hold any less enjoyable, so they were fine. Further in the hold, 1N 2W was very interesting, along with the secret Pandora's Box room and the serpent rooms right before the end. While I usually hate serpents with a passion, I enjoyed 1N 1E, perhaps because it did not rely on guessing the movement of the snake.
I have found 1S 1W to be disappointing compared to its sibling room (2N 1W), and 1S felt somehow lacking too (perhaps because the mother is too easy to reach?). Again, they weren't weak rooms, but simply puzzles which could have been expeded somewhat, I think. I much preferred the last room of this level, 3N 1E, especially compared to 2W in Happyhouse. Overall, Impossible Cubes was more balanced than Happyhouse, with less of a difference between the best and the worst rooms, and a much tidier layout.
Killing Jar was my favourite among the three initial holds, so I will have very little to say against this level. The square around 1N was the part of the level I found to be the weakest, but those rooms shine when trying to play in an efficient manner: while 1N 1E is a very easy room to handle, doing it quickly is another matter altogether, adding quite a lot of spice to the room. So in the end, I think 1N is the only room lagging behind the rest of the level, only because of the "
unnecessary"
trapdoors not near the force arrows. Still, I gather it was needed for aesthetics, and 1N is nowhere as awful as Dugan's level 15, even for players who share my hatred for trapdoors.
I thoroughly enjoyed all the other rooms on this level (2W excepted perhaps, where I preferred the Impossible Cubes version of this puzzle). Rooms like 2S or 3W were plenty of fun, second only to the secret room, which worked quite well I think. A very worthwhile level, when all is said and done.
But Jigsaw Feeling ultimately beat Killing Jar in my heart. I will admit I had strong reservations about that level at first, given how I generally feel about trapdoors, but your level was simply good. All the rooms were interesting and fun, and no matter how I try, I cannot find anything to fault with that level. 2W has a "
swimming against the tide"
feel to it, 3W is a nice variation on the "
lead monsters around"
variation, 1N 3W has a powerful concept behind it (especially the first part), 1N 2W is a great use of trapdoors, and 1N makes excellent use of tar, black doors and trapdoors. A truly good level, worth a 10 in my opinion.

× A note on the Unrest: you wrote something about it for "players who have found all the secrets", but the Unrest can be accessed once all four levels have been conquered (I know I conquered the Unrest before I found those last secrets in Happyhouse). I wouldn't know if you had intended it that way, or if you wanted Master walls instead of those blue doors.
The other three levels are much more open and convenient to backtrack in.
Good catch. I was thinking with the green door there I'd be good, but as soon as it's gone... 
I've got a fix for it, along with some better placements for a couple comment squares on that level, but I'm not sure how to go about updating.

) I'm still a big fan of TScotts holds, and they get some of my highest personal ratings.
