Thats too bad, Family Matters is really a good story, definitely in the top5 for me, hope this is not the case you've mentioned.This Dev has abandoned 2-3 games already, so i wouldn't be surprised if this one was abandoned as well since there are no words of update or anything on his patreon since last year.
So don't hold your breath.
However, is there any way to contact the Dev for some more info?
