Only if you release the pad/stick. That video is basically a dozen different ways of showing off the same two issues:
1. Sonic is at all times equipped with midair-brakes when your pad/stick is neutral.
2. When low on momentum, hills will cancel your movement outright instead of resulting in a back/forth motion as in the Genesis.
The first is awkward for veterans, but workable (and even exploitable; jump to quickly stop). The second is a MEANINGLESS aesthetic issue, not that I expect much from a group that's still bitching over eye color.
I feel so privileged that I got that because of 90's childhood.
Anyone who reads the Archie comics would get that, but props to you anyway.
SatAM was scootin' and rootin', for sure.
