Hyperspeed Slide Kicking
Hyperspeed Slide Kicking (HSSK) is a hyperspeed technique where Mario builds up speed by slide-kicking repeatedly against an unreferenced wall.
Setup
Mario is usually placed on the ground in the concave corner formed by 2 walls, so that he is running into the unreferenced one. By repeatedly slidekicking and recovering, Mario can build up a maximum of ~95 speed on normal floors and 282-400 speed[note 1] on slippery ones (at that speed he will break through the wall).[1]
Shell Clone HSSK
Mario can also be placed on a shell clone instead of on the ground, as shell clones allow him to slidekick instantly without recovering. Since he does not lose speed from recovering, the maximum speed achievable is again limited by the wall, so he can build up 282-400 speed[note 2].[2]
Notes
- ↑ With axis aligned walls, the most distance Mario can move while still hitting both walls is when facing exactly 45° into the referenced wall, allowing 200*sqrt(2) ≈ 282.84 speed. With perfect wall projections with walls ~45° off from axis-aligned, it is possible for Mario to move parallel to the referenced wall while still touching its hitbox for 100 units, allowing 400 speed.
