This game is, it seems, written in Esperanto. I thought it was Portuguese at first, but the game itself corrected me.
You are Alice, and, I believe, you are headed to an Esperanto-speaking conference, where you meet someone who tells you about Esperanto. I learned that Esperanto has between 100,000 and 1,000,000 speakers. Given that the number of Twine fans is probably somewhere in that range, too, and the intersection is fairly low, I don't think many people will be able to complete this game.
I only got through the first third of the first chapter. Looking through the code, it seems like there is a compelling fantasy element in the middle.
This is an intriguing game, and a great amount of work.
