the saves are in the game folder. copy and paste them in the updated version folder.
I did it on pc and it transferred fine though manually just copy and paste the saves folder since it doesnt create one till you actually make a save game so,
I gotta say I've been playing this game and keeping up with it since it came out I'm so amazed by how far its come and I'm happy you produce the content you do I thoroughly enjoy the game. Thank you runey
