You need to manually install the fonts in the font folder. The game will not auto install them and never auto installed them. The bug in 1.0 originally was that I did not ship the game with one of the fonts needed. It is in there now.
not sure if that info helps but I did install the game through the itch launcher so I didn't check the game files at all before launching the game, which is admittedly a user issue on my end I realize, but yeah putting some disclaimer on the store page might help with some confusion. anyways the game is running perfectly fine now looking forward to this :)
