this is just a route of what i feel is best to do for each level when you're first getting started with the category. this doesnt provide any videos, only what levels to play and the characters best fit for it, along with some basic notes that i felt like mentioning. eventually, i'll submit something more complete with replay links and other bells and whistles, but until then i feel like handing this out. also follow along with this for some of the less clear nexus movement i name in here: http://www.speedrun.com/Dustforce_DX/guide/zn31c
this route with slight modifications is what got me my 38:15, but when aiming for around sub 40 is when i would recommend switching up this route a bit. any other questions about this should be directed to me on the dustforce discord; that's the only thing i really check.
