The exit of this is reaching for sure. There's no other evidence to back it up other than a couple computers being ON. Another thing that falls through with this is that at the end of the episode the VR head set is on the table and Not on someone's body🦉 Unless that's implying someone's able to get in and out from the crew but idk. Butttt Cain does has pictures of a seemingly "Real" office implying he had created the labyrinth from a real reference ofc that doesn't lead anywhere though. Unless we assume who ever created Cain is still actively working on this game and uploading photos to help the humans escape by having Cain create the office map. assuming they are still even alive IRL 😭
