@mahtan i think the God is super AI who controling the world, Developers and programmers now just maintain the servers and the AI, then that AI is who controling the world,
if i'm not mistaken, on early chapters the Long princess ask the developers for want to come out early (before Long kingdom released on the update) since she curious about MC that make her 'sister' (the fairy Queen) fall in love with him, so i assume the AI's super advanced on that game...
in fact even MC doubting that this is just a mere game, since it feels so real for him... lol
