The reason Free Fire left the Play Store was that the game was influencing some people And I tend to play a lot of Free Fire or even those people who played the game for many hours committed suicide 😳 and some even went so far as to say that it was their fault of the game since we know that online games are dangerous and we also don't know who is behind it but nowadays online games are known for people to communicate with other people, there are even people who even said that the fault was the reports of people playing free fire and after people play free fire they start to hear strange noises 😨 coming from the backyard or even the kitchen
