V0.22.3 is the current latest update. The game itself is not complete and a lot of recent updates dont actually progress the story, so its hard to say what part is "100%"
I play on Android, and my progess stays. I download the new file, extract it and it updates the game to the new version. Although on PC i think so long as you dont delete the internal save file from your device, it should be fine. Dont quote me though, ive never had an issue with CK
