Try to install it without uninstalling the old version, it should overwrite and save your progress. If it fails to install normally, you have to do a workaround to keep the save.
Open file manager and go to android>data>com.cryoxxx and grab your saves and copy them somewhere. After that, uninstall the game and install the new version. Then open the game, close it, and paste the old saves back in the save folder.
It sounds complicated but its really easy
