yeah the trouble with making the horny part be the fail state is that i am also a fast typist and the meter wasn't over 1% until right at the end where i missed a hyphen or something and it got up to 5%. for the first few passages i wasn't even sure if the game was working since it was at a flat 0% :)
i think it's really clever to have a tedious task as a distraction, especially one i am genuinely doing myself! and it's doubly clever to make it be the manual so i get free worldbuilding that i'm definitely going to pay attention to. it's a shame that a player doing it well means completely missing out on the whole point of the game but i don't know what you could do about that, unless you deliberately rigged the difficulty to make the game nigh impossible, but that might... change... the tone...
