I'd like to add that the new page that pops up for downloads doesn't include the "alternative download" checkbox, or whatever it is, and as a result, I can no longer download anything from the site. I've never been able to use itch.io's base download system, and that's when I've completely turned off all ad-blockers, firewalls, etc.
I'd love to continue supporting all the great creators on itch.io, but it's a little hard to do that when I can't download anything. It's a good thing I didn't purchase something only to find out about this clear error, or I'd be pretty livid.
