Not sure if you still need help since you posted this a month ago but iirc, it's hosted on MEGA, right? You have 2 options:

1. Download the MEGAsync app and then select to download it via the app. The download process will be stored through multiple days until finished. (should only take 2 days as the free daily limit is 5GB)

2. Create an account and purchase a 1 month Premium Lite without renewal. This choice is good if you plan on using MEGA more than on this 1 thing. I do this a few times per year as sometimes my downloads just pile on a little bit too much in the app.

Please disregard. While it was throwing those errors during extraction, the game still ran perfectly........and I loved it! Wonderful writing and the animations seem so much better! I hadn't heard anything about this story in a long time and had started to fear I might not. But now I see what took so long. Fantastic work my friend. I will wait patiently for the rest. Bravo!
