I haven't updated the game since 0.12. Is there a way to update the game to the current patch? The read me says I need the most recent one.
you can download the recent patch above
You're reading the update patcher notes.You can just update the game exactly the same way as you have before - download the new file, delete the old. And as always, if on Android, please move saves over so they don't get deleted in the process.
