There are no limits! You can write as much or as little as you want to :)

okay second question and hopefully final. I had started writing a twine story/game a long time ago (that will not be submitted it'll take me five years) where I was taking advantage of the digital format to store and track variables, changing the phrasing or the situation a little depending on previous variables. Is that allowed for this jam or should I try to keep towards 'if this was printed it should be playable'? As near to classic gamebook as possible?
