The Elder Sister is a text game made in Twine that was done for a game jam commemorating the 150th anniversary of Alice's Adventures in Wonderland, one of my most cherished books. In this game, I decided to create a tale that happens after the original story, following Alice's older sister Lorina, who gets trapped in Wonderland and must deal with the turmoil created by Alice's presence. Along the way, she needs to convince the denizens that she is not herself Alice, put things back in order (such that Wonderland has an order), and learn to take life a little less seriously. This installment went through the first chapter of the story, The Hall of Doors.
You can play the game here (opens in a new window). The Elder Sister was made using Sugar Cube in Twine 2, in addition to some CSS styling and JavaScript.
