Yes I know I'm not a beginner but this seems pretty simple. I've created a pretty crazy font, which I like, but it's hard to read quickly -because it's crazy. I'm finding the default speech delay is set too quick: is there a way to reset it so that speech text automatically displays longer?
Game.TextReadingSpeed (http://www.adventuregamestudio.co.uk/manual/Game.TextReadingSpeed.htm), changes the speed AGS assumes the player is reading at. Lower value means text stays on screen longer.
That said, if the issue is with the legibility of the font - not that it's unreadable necessarily, just that it takes more effort - you may want to consider changing it so as not to turn players away from the game, however much you like it. (But this isn't the critic's lounge...)
EDIT:
You may also be interested in Game.MinimumTextDisplayTimeMs (http://www.adventuregamestudio.co.uk/manual/Game.MinimumTextDisplayTimeMs.htm), to set .. well, what you'd imagine it sets...
