Bunnyhops
From Celeste Wiki
Bunnyhopping is commonly used to refer to the act of performing short jumps. When initiating a jump, Madeline gains a small speed boost.
Usage
Bunnyhops are frequently used in combination with other maneuvers, such as hyperdashes, in order to gain additional speed and height. They are also used by speedrunners during the Prologue, since repeatedly performing bunnyhops saves small amounts of time.
