Hi! So I literally just realized that there isn't a keyboard shortcut for autoforward, and it has to be placed as a button in-game. There's a slider in the preferences that says "auto-forward," but it doesn't work without the button. This is my mistake, sorry!
Apart from using your mouse, you can also press the spacebar to advance text - if that will help.
Thank you for all the kind words! We worked hard, and it is nice to see that it paid off. :)
