It's been a month since I played the last update 0.3 but I can't get off my curiosity about the ending since it's so mysterious so I've got a theory who's knocking behind the door. My first theory I think its the ghost in mc's dream tho it has a huge plot hole but I consider her after all the mc already could manipulate his power far enough to use it in fights but maybe too early to meet her. Second theory it's Chang because he is the one who makes the plan and I guess he have enough money to buy a neural implant for himself since he has a job. Lastly the third theory it's a npc that they might triggered while in there.
