Yo this is some sick art. Also a question, I have the game downloaded on android, version 0.9, once 0.10 is out can I download it without having to restart? Cuz that would suck.
I presume you mean the upload feature in the saves menu? Can you describe the problem you were facing with it? It's supposed to generate a temporary code you can then use on another device.
Saves will remain on your device until you uninstall the game, so if you simply update using the new APK without uninstalling, your saves should still be available.
