If I remember correctly you're using a smartphone but playing the pc version istead of the android version, right?
I never played on smartphone, so I don't know if this could work, but:
1) Download the version 0.44 for android. In your version 0.43 for pc there should be a folder "game->saves" copy all the saves and paste them in the relative folder of the version 0.44 for android.
I don't know if the relative folder for android exist. If it doesn't exist
2) Try to open the game (0.44 for pc). Tecnically you should have your saveslot automatically transfered from the 0.33 version.
If all your saveslots are empty
3) In your version 0.43 for pc there should be a folder "game->saves" copy all the saves and paste them in the relative folder of the version 0.44 for pc.
I suggest you to switch from the pc version to the android version, since it should be optimized for smartphones.
