Here we go, the Android version is finally up.

If the game doesn't want to install as update:
Make a backup of your saves. Saves files are located under: Android > data > weird.shit.is.going.to.happen > files
(If you're on android 11 open up the system Settings, then navigate to Storage and click "Files" to access this folder)
Copy the files folder somewhere else, delete/uninstall the game, install the new version, start it once (might not be necessary), then put the files folder back in place.
This way you can use your old save files even if you have to install as a new game.
