The main train gimmick is quite unique and leads to interesting ways to deal with patterns outside of raw movement.
I found the camera while not sprinting to be too close to your character, and the camera movement when moving from one side of the train to another was pretty jarring and gave me a bit of motion sickness. I ended up handling a lot of patterns by sticking to one side of the train for as long as possible (to avoid dealing with the camera movement caused by doing so) unless I was forced out of position.
3D danmaku (and signposts) is fun to see as always though I had a hard time with depth perception, especially with the pattern where it descends on you since the bullets have no shadows on where they will land on the ground.
