Me and My Family

Me and my family have continued to play this game as well as your other game ‘that’s you!’ Even after you took the game off the PlayStation store. I really hope you can reach out and get PlayStation to add it back. Because I’m introducing this game to a lot of my friends and family members who have never got to play it and they would all like to buy or download it themselves.
