I have found a way to transfer saved games on interstellar pilot, until they give us cloud save, pay attention.
Phone\Sdcard storage, look for the folder that starts with "com.pixelfactor....." copy it and zip it, then back it up on google drive or drop box. For more in depth explanations mail me at "ajide.archilles@gmail.com" this is not a joke!!! This is the real deal I've been playing the damned game since forever, transferred progress to over 5 phones now lol, mail me for more explanay
