When I played Dark, the stars in the background were a little distracting (at least for me) since they’re really bright while everything else (except for those white orbs) is dark, and it made it kinda hard for me to tell the exact shape of the course and where exactly to go.
If the stars overlapping with the course were darker, I think it’d help a lot with being able to see the level a bit more clearly. Here’s a (poorly made) mockup image:
