Changing the colours and fonts in Alan 3

I’m just trying to change the colours and fonts in the Alan 3 IF game but they’re not working. The colour won’t change at all (it’s stuck on black text on a white background and I don’t want that). The fonts will change but the moment I exit out of the game and go back in they’ve reverted back to their old style, which I also don’t want.

Is there an option I’m missing to change the colours and permanently change the fonts?

Will it run in Gargoyle?

I haven’t tried yet. I generally steer clear of Gargoyle because it requires me to edit text files to change the settings and I find that a pain, but I guess it’s something to fall back on if nothing else works.
