Have you updated to the latest Android versions of both seasons? Season 1 needs to be run once to get the saved games to a new location. Here are the steps to transfer your Season 1 save to Season 2.
- Install both the new Season 1 and Season 2 builds on your device.
- Open up Season 1 until it has gone to the main menu and close the application again.
- Verify that a directory called RenPy_Saves has been created in your Documents directory and that it has a subdirectory called com.perverteer.tftuv. In that directory there should be a file called Season_1_*longstringofalphanumericcharacters*.save
- After verifying, open Season 2, from the main menu you should be able to select Continue and play with your Season 1 save.
