I mainly run normal mode and switched to icebreaker and want to know how jumping off the edge onto the walls makes you go any faster cause im getting hella confused

also i dont know how to do it lol, i don't understand

On some maps the platforms slightly overlap each other. So to avoid players standing on them the devs made them into ice platforms. So they act like normal ice. The same goes for the top of some towers. They will have ice on them so you can gain momentum.
