I completed till the story where a bear chases the mc and kanae. I don't know what to do after that. Is there a quest menu on what to do? Or how shall I progress?

The last event in public version is either that or with Beth in the bath. Better progression tracker is in version v64.

How should I go about unlocking the farm and or ruins? (I got to the free roam after the whole getting trapped in the snow globe thing)

Have to follow the tracker.
