aint got this on recording and i don't know how i did it, but you can skip the miniboss in nitra fleet, or the third level in nitra district level 3 through a mix of dashes and upwards attacks. (because they slow you down while your dash recharges) it might be able to be used elsewhere? seems niche though.

Which boss exactly? the wasp thingy or the other thing (i have no idea what to call them lol) and did you use the dash + upper attack to maintain height or what exactly?
