Hey, though I haven't finished yet, I have managed to translate the code and get it to work!

First, as Dino mentioned, you have to download the game jam build here: https://dino999z.itch.io/therapy-with-dr-albert-krueger/download/eyJleHBpcmVzIjo...

You are also going to need Visual Code Studio installed, as it's what you're going to use to edit the Renpy rpy files:https://code.visualstudio.com/

Now, in the game files, you are going to see many "rpyc" files, these are the script, though you cannot read them as is, since they were converted in a way that the computer can read them more easily. Which is why you have to convert them to "rpy".

To do this, use https://grviewer.com/
Drag and drop an rpyc file and then download it, this will turn the rpyc into a rpy file, and you can now open and edit it in Visual Code Studio.

Once you're done with editing, simply move the new rpy file into the game folder and once you run the game, it will automatically convert itself into a rpyc file and replace the old rpyc.

If you want to access the images, you can do so by drag and dropping the rpa file into https://grviewer.com/ or by using https://iwanplays.itch.io/rpaex, which extracts all the images, videos and audio out of the rpa file.
Once you've finished editing these files and you want to convert everything back into rpa, drag and drop all of the edited files that used to be in the rpa (in this case, these would be the folders gui, audio, images and the files: HORROR.webm, SKELETONS.webm and _FAKEAD.webm) and drop them into https://grviewer.com/

Then, go to "file" and "Export...", select the mentioned files and convert them to ".rpa". Make sure you name the rpa file the same that the original rpa was (in this case, archive.rpa) and once you got it downloaded, simply replace the original with your edited version in the game folder!

Btw some extra: if you need to change the font due to language difference, use this: https://www.glyphrstudio.com/online/

The font file is located in the game folder and ends with .ttf
