The first half of the message turned out fine, but the second half was unfortunately mangled by my errant handkerchief flourishes. This doubtless caused my faithful magician character to revise any plans to move on to sawing assistants in half.
It all looked forced to me except the final "room" (which, needless to say, I did wrong the first time, trapping a box in a corner)--I think you can choose to weave up/down/up or right/left/right, basically.
That is what I was going for - my intention was for only the correct punctuation to be solvable, which I think is the case but I might be missing something.
