### 5/5 — Me and My Family

*2025-03-24*

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.

### 5/5 — How to play on PS5

Open the app, when the error comes up that the playstation isn’t found. Select the option to join another way. Select join through IP address. Google how to find the IP address of your PlayStation. Input the IP into the app and it will connect.

Not ideal but a work around.
