The endings aren't complete yet. Each ending will get a full update devoted to them to finish the story.The endings were short except the one with mum. It would have been nice with a long harem ending with sis/mum/Haley and Rosa. That would really have been fun with all of them pregnant .
In 0.12 the Karen solo ending got the finishing update.(that's why there's more content compared to the other endings)
That route is finished but the others will still get 1 full update each.
