neighborhood 3 Final chapter

I felt like I struggled with what was reality and what was in game throughout the story especially with the end closing in it blurred the lines for me a lot. One big question that the end brought up for me was were the kids so in their games that they couldn't tell reality from the game because at the end blake killed his mother , or were things that were happening in the game actually happening in real life which is why Joy found Codys mother outside. My theory was that the game was creating a parallel universe where the game was no real life. Or maybe nothing ever happened at all. What if in the end the mother that we read about was actually in game, and he killed Joy in game and when he did he got so scared he snapped into reality, asking for her to see if it affected him in real life. Also if I am right about the game coming to life what happens to all the parents to they become zombies eventually like they are in the game, or do they just not exist anymore. Still plenty of blurred lines like I mentioned I'm hoping that watching the play answers all my questions.
