Juat a copy paste from patreon public post:
MERGE YOUR SAVES FROM THE OLD VERSIONS TO THE NEW ANDROID APK
The new saves will be in: "Android/data/com.komisari.hhg/files/saves"
You might need to use an external files app or a USB to a PC to access those files
Find your OLD saves in "Android/data/0011/Org.HHGv0.12.001"
Copy all those saves and drop them in: Android/data/com.komisari.hhg/files/saves
Play the game
