The Social-Fi system in Moovy allows players to connect with each other and form a community within the game. This is made possible through the integrated BBChat feature and the ability to interact with other players online through various means. With BBChat, players can communicate and share tips and experiences with each other in real-time. Players can also view each other's profiles, which showcase their avatar's statistics and achievements. The online map allows players to see other players' avatars and interact with them through friendship requests and chat. This social aspect of the game creates a fun and engaging environment for players to explore and enjoy together.
