seeing how regions are merging already, i'd say that all of earth was already united in round 20 he** maybe even other dimensions were united with them which we will not know till later on, because already there aren't lots of people alive out of the ~2b people that were taken.
also from the start we already saw that the angels were malicious and they killed without care but even then, the game wasn't designed by them as they are nothing more than pawns, i think the one that designed the game is a divine being or even just the will of the universe.
