For every android user who wants to copy the saves over to the new one
your old saves should be in :
internal storage/android/data/harem.hotel/file/saves
copy and paste everything to :
storage/android/data/cyou.joiplay.renpy/files/harem hotel/saves
after you have installed Joiplay/ the extra renpy plugin from the playstore for joiplay, and unpacked the pc game.
Works like a charm for me. Sometimes the initial loading in Joiplay takes 2 Minutes to load.
