I did like the fact that there were many different hells with punishments based on the religion of the person. Like say your religion doesn't believe in hell then there wouldn't be one. Also like the religious currency, that one was kinda funny.
I loved the variety cause even if every religion believes they are the one and only, what matters is the heart, so this was a good illustration
I think a lot of this story's world-building is based on Korean Mythos' and syncretic religions' description of the afterlife as a convoluted bureaucracy. Not sure how often manhwas are inspired by that particular aspect of the culture since this is the first one I've read that leans in heavy to it but there are probably others. You do see Western authors taking this approach (ie. The Good Place, Terry Pratchett's writing, Welcome to Hell) but I think in Korean culture there's an actual folklore precedent for it
