In the online version 6D has "sarply" which should be "sharply". Whew, this puzzle was a bit of a slog! A couple of laughs (which I always want in a puzzle, so Paul's my favourite) but otherwise, slogsville.
I'm afraid I must agree with the general sentiment. I'm 3/4 through it but can't be bothered finishing it. Several that I can't parse but again..... all too 'clever clever' but no fun (for me).
