if you meant the source code of the game. i decompiled the game with "AssetRipper", which extracts all assets of the game. it doesn't work in unity correctly tho. but that's where the names are comming from

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. :)
