Phew, I did it again, and I got to Rule 33 (so 32 was the last I made). That's a big improvement from 25 (which was my previous record). But that was already incredibly hard and the additional constraint made it basically impossible for me. So I looked up how many there are, and damn… I really almost made it. Although those last constraints really make it that hard, someone really finishing it must be insanely good and persistent.
