The charged blast in blast mode acts as a jump. You switch modes by pressing spacebar on desktop. A good maneuver to get used to is charge blasting relatively downwards, switch to hover mode, and continue your momentum upwards.
I tested the map both in VR and desktop extensively and in desktop it is very much completeable (My fastest is about 4 mins on desktop). At some points you will need to look backwards but for the most part you can get away with aiming straight down.
I'm glad you got to try it :) I hope you can make it to the end!
