I'm confused but kinda not? Like I understand basically every character was an actual player in the game at one point and I guess relied on their tapes not being taken out to keep their memories?

But then I have to ask, where are their tapes going, like who's taking them out? Because the new player (forgot his name) only got his memories back because pi bada put the tape back in. So like, who put Pi badas tape back in and gave his memories back?

Or like are they all playing the same game but in different parts?? I'm so confused.
