I won’t go that far, but that’s just basically the idea behind what’s happening there. I get that maybe you’d want to make sense of it, I also question stuff in games or movies, but in games, arcade games specifically, I generally just go with it. It’s kinda like saying that Superman should have been able to catch those missiles… 
I’m definitely not trying to be super realistic in any way about it. Even a small plausible hint at something is good enough. The fact that he gets tired has no relevance it’s just in my head what goes on, you know. I don’t ultimately care if anyone else knew that.
The real question is… why is he there to begin with?.. it’s a game… I put him there…
