My issue is that the code for the adjusting text doesn't seem to do anything after I tweak the parameters . Might be because I am using Ren'py 8.1.1, maybe? Version 8.3.4 isn't too far removed from it, however.
Sorry, should've been more specific. It didn't work before and after I adjusted the parameters.
I changed text_size_minimum and text_size_maximum to be -5 and 0 respectively. I additionally added the text size dynamic into gui.rpy. No effect occurred for each change done.
