The thing is, however, is that Caine is constantly and consistently stated by all of his creations to be their God, hence why he scales above them in power. Yes, Caine is egotistical, but he's still above his creations according to them. I disagree with the nuke.
I also disagree with this. Just because the Moon and the Sun are the same size doesn't mean their feats of moving are completely unusable, it just means that they are not the same size as a traditional sun and moon especially with how they appear in front of clouds. We also don't have any evidence that Caine wasn't given any density values, meaning that these densities of the Sun and Moon should still be usable. Furthermore, the Sun and the Moon are sentient, whereas every other object that lacked proper physics was inanimate.
Don't have much to speak on this, so I'm neutral here.
I also disagree with this. Them being harmed by guns only means that the guns are at their level, not them being Street level. Not to mention, the cast has been known to withstand just about everything that comes at them thanks to their immortality.
Alright, let's downgrade Doki Doki Literature Club, Pixel Gun, and Sword Art Online because they take place in virtual worlds!
In all seriousness, this is a bad idea. The whole point of the show is that the main setting is within the PC for 99% of the time which shows that the PC is the baseline reality, and any feats done within it should be fine to scale to the real world. Verse equalization is a thing, you know.
