Okay, so I don't know if many people will see this, but I've learned that the score is the sum of the value of each unique letter in alphabetical order, so, a - 1, b - 2, and so forth. The score is the sum of these numbers added together, but it only counts a single appearance for each letter, meaning, if 's' appears twice, it only adds its value once. Also, there are a total of 13 unique symbols on the first page that the player encounters. Those symbols are, " / * & § # . \ + | % ^ and also, in a pattern below, -
For comprehension sake, they are Quotation Marks, Forward Slash, Asterisk, Ampersand, Section Symbol, Octothorp, Period (Or Full-Stop), Backslash, Plus Symbol, Vertical Bar, Percent, Caret, and Hyphen respectively.
Now, everyone is assuming that 30 * 26 is where 780 comes from, but, I think that's not quite the case. Is it a coincidence, I don't know. But I'd like to point out the sum of 39 and each number before it to 0, is also 780. I think it's interesting to note that there are 26 letters in the alphabet, and there are 13 unique symbols on the first page. Which would put us at 39.
