I've been playing VV4 for a couple of weeks now and absolutely love it!
Even though I've solved all the puzzles and most of the trophies I'm still very much into the game which hasn't happened before.
I'm having a hard time with the collections though. The flute collection was easy but the rest are still unfinished. I still need two mural pieces but none have appeared in days.
At this point I'm just enjoying making babies and seeing what they look like. I'm trying to make a blond baby girl but that hasn't happened yet.
Anyway I love this game and hope there will be many more versions in the future.
