I don't know if this has been asked before but, if you release future updates of this game for download, is there a way to transfer saves across versions or would I have to start again?
Ive kept my save since .12 or .13, should work across updates. Its a little harder to track down on moble if you want the physical save, byt still doable
Crimson road is right. I'm not super familiar with the save structure on android, but you can copy the save files from one version to the next and there shouldn't be any issues with the game.
