Friendly reminder that you can still access the site via Tor, simply access the official GoG-Games Mastodon account and copy the address where it says 'Tor', now copy the address into the Tor browser and that's it!
Remember that you should not download the file through Tor, you should simply obtain the file address to download it through your regular browser.
Sometimes it takes a long time to connect or gives a connection timed out error, but at least for me it eventually works after a while.
Edit: Stop upvoting me, it seems they not only deleted the link to the tor site, but when you try to access it, it tells you that the site doesn't exist anymore. :(
