Hi, sorry for the confusion! We put out a dev update for this last month but I realized we forgot to change the info at the top of this page. We removed the old gamejam version of the game as we will be adding new content, voice acting, and 4 additional routes. The only version of the game available at the moment is the prologue.
However, if you'd still like to play the gamejam version, feel free to send me a message and I'll give you the link :)
