You can't follow the story because of the missing video sequences. So you need to add the Media Foundation DLL. So I followed: https://www.protondb.com/app/462780#1SZt3q1I5K

But i needed to do some Mint specific changes:

• First i need to install a valid Python Installation (in my case Python 3.10). Step 4 mentioned to replace all appearances of python2. So if you installed Python 3.10 via apt you need to replace the python2 with python3 if you haven't a second alias for it. Default on Mint is python3.
• Second change: cabextract can be installed via apt. So you can simply skip step 5-7 and replace it by a simple sudo apt install cabextract

Addtion: In Proton Experimental there seems a change to the directory-name of dist - so if you want to use the Script with the experimental proton, you maybe need to replace the dist folder to files in the install-mf-64.sh, too. (untested)
