If you play on PC, you can delete it, if you want. After you download the new version, your old saves will still be there! (Windows stores the saves in a different location)
I'm playing on Android, so I don't know what to do when there's an update. When will be the next update btw?
Then keep the apk installed and overwrite it.August on Patreon/subscribestar, September here
okay, thanks!!
