Bigger hint for 32: for “letters,” you’re not so much looking for a synonym, but a subtype
And even bigger if that’s still not doing the trick: it’s “letters” as in “characters,” not “letters” as in “missives”
51 is a fun one, but fairly obtuse:
there’s nothing special about the names or any of the punctuation, except for the period.
each word is important, but most of each word is unimportant
in fact you only need one part of each
60 is a bit more of a you get it or you don’t, so it’s hard to hint at without spoiling completely, but thinking a bit meta might be helpful
I still have 52 and 59 to figure out as well – and I need to grind through 55, though I think that’s just a matter of putting in the elbow grease.
And 61 you say? I’m only up to 60, so guessing that has something to do with beating the boss perfectly and/or sussing out what’s going on with the colors…
