This is a port of Squake Reforged to the 1.21.1 game version for NeoForge.
Squake adds bunnyhopping, strafe jumping, air control, trimping, and sharking, while also eliminating speed loss from fall damage (server-side installation required). Bunnyhopping has configurable caps, and is code is inspired by Half-Life and Quake.
