I think this is meant to be a "combat" trailer, so to speak, so less focus was put on the environments
On the flipside, we got a lot of interesting information on the combat. I noticed Hornet seems to have multiple different basic attacks - she uses the diagonal pogo attack we've seen before in the trailer, but also something that looks very much like the Hollow Knight "down-air" pogo. Similarly, I spotted at least three different attacks she does from the air - a spin move, a neutral horizontal slash, and an overhead slash. There might be a couple others, like a heavier overhead slash I'm currently assuming is like the Nail Arts from HK, and a different looking spin move. There's also two new ground moves - a dash attack that rebounds Hornet after hitting an enemy, and an uppercut that gets her airborne
Basically, combat seems to be greatly expanded from Hollow Knight. I'm not really sure how all these options are going to work in game, maybe it has something to do with the Crest system we've heard about from previous updates? I think I remember them saying that Crests could affect Hornet's core moveset as well as giving her equipment slots.
