EDIT warning: changing the font has broken a dialogue with the raven, so I had to go back to the standard font for this dialogue. I can't reccomend anymore that you modify the font.
I find the font in the game really ugly and hard to read. If like me you want something more readable, rename Bankir-Retro.ttf to WALSHES.ttf,or try a font of your liking that might be working.
