Oh, good - I really couldn't explain it, since the only mechanic that isn't already in use in the intro is not in use in the default mode.
Does the intro still present itself as going over the screen? If so, you might want to play around with the line 671
tFont=TTF_OpenFont( "arcon/Arcon-Regular.otf", DMode.h/27 );
increasing the dividor (def 27) might do the trick.
