Review Detail of Clockwork_Jester in Overlord: The Origin

This story starts out very strong, with the MC amassing a lot of power in the game world prior to the shutdown in ways that mostly make sense. My problem is that once the shutdown hit, the MC suddenly becomes a lot weaker than he reasonably should be, based on his accomplishments up to that point, and he's completely separated from the rest of Nazarrick. Not saying you can't make an interesting story around that premise, but to me it felt like a slap in the face and had a sort of "all your trials are meaningless" implication.
