Whats the process for updating the game but maintaining saves?

If you’re on computer, you can use the itch.io launcher to download and update the game.
But if you download the new version and launch it, your saves should move over automatically.
As for phones, download the apk and install as update. Don’t uninstall.
Other people have answered you, but just so there's an "official" response:
You don't need to do anything to maintain your saves - the game will do that for you automatically no matter which version or method of updating you're using.
Just download the game, extract to a fresh folder if you're on PC or overwrite the APK if you're on Android and play! That's it :)
