Do you know what the source of this game is to download it? I'm not referring to the title, I'm referring to the name of the objects, game modes, etc.

All the translation key (the text itself) is in the normal compiled game. its in the game directory then "/BALDI_Data/StreamingAssets/Subtitles_En.json". You can change the text and it will work without any mods.
And the font is in the assets under the name "Comic_[something] Atlas.png
I hope this is the right thing you wanted. :)
