Promising game with a very interesting story although there are a few bugs.
In general you should store the pronoun sets as ints and use if macros to replace the entire sentence.
<<if $pronouns == 0>>\
They are hurt.\
<<else if $pronouns == 1>>\
She is hurt.\
<<else>>\
He is hurt.\
<<endif>>
You also should use "\" at the end of lines to remove the empty space created by them.
At the end of the second chapter in the tavern shortly before leaving the city the pronouns get reset to "she/her".
