I recently found this YouTube video that shows off the early prototype of Candy Crush Soda Saga from 2013, called Stritz. It was made for iOS. I can't post link due to my community level, unfortunately.
As seen in video, there are many interesting things in this prototype!
For example, instead of Kimmy, we have Biffy, or instead of Yeti, we have bears. But all other episodes are the same, actually.
I really find it interesting how today's Candy Crush Soda Saga looks nothing like prototype. In fact, it doesn't even look like 2020 version.
