hmm, I must say, seeing no obviously new environments (at least that I could obviously tell on one watching) is a bit disappointing. Ketheric as well doesn't scream intimidating antagonist to me as well. It seems odd that the entire first act is seemingly not going to have any direct contact with the main antagonist.
Oh well, at least it's coming soon and we'll be able to finally figure out what the hell this game is lol. Despite my misgivings, I'm looking forward to playing the full game.
