Finished the hold. I'm usually too lazy to rate, but this didn't have any ratings yet so I tossed my quick opinions.
Rated this 5 brains. Most rooms didn't give me much trouble. The ones that did were usually annoying rather than difficult, and there was always some approach that wasn't too painful to execute even in those rooms - it's just that there were a handful where I ended up doing something annoying for a while before I saw the not-so-painful way. The Magic Wand level is maybe a little bit harder than the others.
I give it a fun rating of 8 - the gimmicks are silly and most of the rooms do interesting things with them. This would be higher if not for the few annoying rooms. It was still plenty enjoyable, I just ran into a few rooms that I didn't want to deal with when I first came to them.
The main reason I was posting here, though, was to note trivial rooms that the architect might want to consider marking unscorable.
