Here are the two current routes for any%:

The Pincushion Route :

• World 1 : no Nyquist / (1-7)
• World 2 : all the levels except the last one
• World 3 : (3-1) to (3-8)
• World 4 : no Work Harder, Not Smarter / (4-7)
• World 5 : all levels except Diamond 2 (Diamonds' Revenge)
• World 6 : (6-1), (6-2) and (6-4)
• World 7 : all levels except (7-6) and (7-7) and the three last ones
• World 8 : only Boss Fight 3, since obviously you don't need to play the first two.

The Pincushion Route is perfect for people who prefer an harder and slower level (Pinchushion) to a luck-involving level (Diamonds' Revenge).

The Diamond Route :

• World 1 : no Nyquist / (1-7)
• World 2 : all the levels except the two last ones
• World 3 : (3-1) to (3-8)
• World 4 : no Work Harder, Not Smarter / (4-7)
• World 5 : all levels
• World 6 : (6-1), (6-2) and (6-4)
• World 7 : all levels except (7-6) and (7-7) and the three last ones
• World 8 : only Boss Fight 3, since obviously you don't need to play the first two.

The Diamond Route is perfect for people who struggle and die on Pincushion and prefer an easier but inconsistant level (Diamonds' Revenge).
