Hey there, I started my game on 0.9, is there a way to just update to 1.0, or would I need to start a whole new game?
you can copy your save file into the new version
Just go to your "game" folder in your Once in a Lifetime folder, copy the "save" folder into the same location of the latest version
If you're playing in PC, your saves should still be there (even if you deleted the game)
