I feel like 100% needs to be split into two categories, or at least add a Route option to future submissions.

"100%" starts from a new save file, and requires you to both collect all 60 Starfish and finish Fishing Net Rescue.

"All Starfish" may start from any existing save file that has 0/60 Starfish, and only the Starfish themselves are required. Levels may be played in any order (though chronological would be fastest), and it is not necessary to finish any specific level during the run.

All Starfish would save time in all the same areas as the Any% NG+ route, with the added benefit of Starfish being saved upon quitting the level. This could be used to skip the Luxo Ball section in Training With Gill, for example.
