For _nova b3, the bonus that has a tall wooden column in middle you wallpogo down as demo, I assume you can wallpogo down most of the way then strafe the rest.
I had an idea which is the same bonus except you need to use 1 sticky only per face of the column all the way down, so you can't recover. Finishing with a single sticky at the bottom. T6 of course.
Also an idea for a TAS where only 1 sticky every TWO faces is used. Not sure if possible. It would look really cool though.
