I kinda agree with the review below mine but I didn't really get bothered by the "bad" elements, maybe except some for the ship parts at 58% and 69% which are a bit annoying.

This 5/10 does not mean that the level is mediocre; rather, it means that the level has both really good and really bad elements, which is by far the most annoying kind of 5/10. I love the progression, but actually experiencing that progression means having to wade through boring gameplay and chokepoints.
