Squid game

My family has been watching Squid Game and I saw something strange on the last episode, so I put the photo here. The hand in this photo is the hand of the main character, there is something in the hand, it looks like a blackboard, but I think it's a microphone, maybe this is a sign that this is a recording, maybe the game is over and this is the reward, I also found a lot of clues in the previous episodes, but I did not take a photo, the main character is standing like a cut-out, the actors are in the same position as the cut-outs, the main character is talking to the actor, you can see every corner of the room but no camera, and there is no door or window. I think the whole game is a recording, maybe it's a movie or a game, and the game is over, and the main character is talking to the actor, but it's not over yet, the game is still on, it's just the level is different, the main character is talking to the actor, but he can't leave the room, he has to keep fighting, until he wins all the games, and gets the final reward.
