Thanks for playing!
The pixel perfect camera component make it look good enough for me. I also update the camera in LateUpdate, but didn't make it to snap to pixel positions and also tried adding some parallax layers but looked horrible.

Yea I came across the Pixel Perfect Camera Component like 50 times when trying to figure it out, but found it didn't completely resolve the issue. Even with that, when game objects AND the camera are moving, there's some timing issue that causes one to update and render just before the other making things appear to jitter back and forth as they move.
With your game I barely noticed, and only did so during the moving between sections. In mine, it was nauseating so I had to get it fixed.
