I started doing a quick change in direction followed by a jump
so If you're sliding down to the right,
quickly press left and jump,
then midair move back to the right
there is a bug, when you jump while running UP a slope,
you get a higher jump
and because I really liked the feeling of that, I never fixed the bug :)
Now I use every slope to jump, which requires quick changes in direction
which forces me to use the unfimilar buttons a lot
feels great
