Glad you liked the game. I think if we worked on the game further we would revisit the font and sizing.
We were worried that larger text would limit the amount we could display for the player on the patient file. Initially I planned to have multiple tabs to the patient file (Front Page, History, Investigation/Examination); however, as time went on we reduced the information to a single page to save time and player cognitive load.
Would you have prefer have single page patient file (as is, or with scroll boxes) or multi-page file like a patient chart?
