Thanks for checking out the game <3
We are using 3 fonts, one of them is only used on the main title. "convincing_pirate"
"black_chancery" we are using as a fancy names font for the boats & "manus_magnifico" we are using as a pixel writing font.
Bit confused about the default Unity font comment as we are not using a game engine at all, all is written in just HTML JS & CSS ( check inspect element :P ).
But for accessibility reasons we allowed "manus_magnifico" to be switched out to your default system font. :D For you that might be the Unity font you were talking about.
In hindsight probably should have used another fallback font for accessibility, It's something we can look at a future jam.
