Small bit of usability feedback: in the options, Auto Forward Speed and Text Speed aren't consistent in direction - to make the text speed instant I have to fill the gauge (pull right) but to make the AFS faster, I have to pull it left, making it empty. It took me a while to figure out, I kept tweaking by small increments and didn't seem to get any improvement.
Ideally, you'd change the AFS to be like the text speed, so it's much more intuitive to know what to do. Some games actually provide a text preview in the settings, but I guess that would be a bit overkill at this stage in development.
(Another solution would be to call it Auto Forward Delay, as making the delay higher makes you wait more, while making it lower makes you wait less.)
