This update had good content, but it doesn't reach its full potential due to a lack of focus. There was a whole lot of events that were unrelated to each other, which resulted in none of it getting the buildup it deserved. The Korra scenes were great, but they were just kinda there, like she was some side character. She needed more screen time - I want to see her reaction after the rope scene to build up the Pema/Asami scene where she finally allows Tenzin into her pussy.
Related to this, there's also a problem of not knowing where to go to proceed since the story is in such disarray. At several times, there's no active plot and you have to just click around the map until you stumble upon something random. (This is made worse by the fact that some characters, i.e. Korra and Zhu Li, can be found in several places.) The usual structure, where you constantly check on the main girl (Korra) amidst short trips to the shop and side characters, is a lot better both for storytelling and gameplay reasons.
I'm going to have to assume that there is no "under development" disclaimer since I've checked everywhere I could think of, and that the Pema/Asami scene with Korra is where the update ends.
