There is Text Document Readme.1 in a game folder, there you can read that "For the game to work install fonts, VT323-Regular and VL-Gothic-Regular, located in Font folder."
There is a Font Folder also, those two fonts are there.
Like with custom fonts, if you'll provide the fonts in the project's Fonts folder it should work without requiring the player to install any. If I remember correctly, including the default Gothic font RM uses is a good idea even if you don't use that font in the game itself at all.
