Just finished "Let Bions Be Bygones" now... Act 2 was a fraction of Act 1, and Act 3 another fraction of that. I honestly barely had any idea what the hell was going on past Act 1, and if I had to guess I'd say the team had to rush to get it finished.
In a way it kind of reminds me of Last Exile, in that it seems like there's a detailed world behind it all, but it's all pushed out too fast with too little explanation so it all seems like incomprehensible nonsense when taken as presented.
