You cannot play on your old safe , unless you retrieve it from the recyle bin in case you are on pc or if you want to continue from the 0.6 part i can send you my save files dm on discord: _darkkk_
Yes please I just sent you a friend request : netzzz005
Just be wary that sharing save files over the internet has anonymity risks for the provider and security risks for the receiver.
