If you are playing on Window, just copy the whole "save" folder to the full version directory.
If you are playing on Mac, just copy the whole "save" folder from
"Worm Nest Plague\Game.app\Contents\Resources\app.nw"
to the same location of the full version.
If you are playing Apk version, some phones will transfer save automatically when you update the app. But you can't transfer the save to / from other device.
