found that if you 2 tap with your back against the spikes you can full jump at a certain spot (i aim for the middle of the 2 rocks in the background) and clip into the stairs consistently. 6 tapping after landing at the beginning is just as fast as jumping into the ceiling, i was trying different things and ended up preferring the former. the way i fall fast at the beginning is as soon as i see the lava part of the pipe on the right reach the top of the screen i hold right
