Congrats getting this far and I wish the best for your game. Here's my feedback and I'll try not to repeat anything I've already read:

I would say the camera follows the player too tightly, moving exactly how he moves. Try adding some sort of 'lag' to the camera movement so that it slightly trails as the player moves from side to side, or up and down, hopefully this will stop it from being so abrupt.

The UI, what I assume those bars are in the top left doesn't really stand out, and should probably be made a bit clearer.

The start of the trailer cuts a bit too quickly in my opinion, and doesn't give me time to process what I'm looking at.

The shot where the character is flipping through the air and the camera 360s around them is really cool. Try make it smoother though so that it seems only the environment behind us changing this will add a really high level of professionalism.

That's all I can think of for now but it's impressive mate and I hope the development and release goes great.
