I don't know my version or loader
This mod adds a configurable keybind to boost your player.
When in-game open the pause menu and go to Options -> Controls -> Keybinds -> And find the "Fly-Hack" category (under movement in NeoForge), and set the "Boost" key to whatever key you want!
While it can be abused for flight, that wasn’t the original intention - I actually stumbled upon it by accident while testing another mod and thought it was funny enough to release.
Although some might try to use it for cheating on servers (which I don’t condone), the boost is genuinely useful for building. Whether you’re in singleplayer or creative mode, it lets you zip around much faster than standard creative flight without needing to constantly adjust your flight speed or switch game modes.
⚠️ I do not condone using this mod for cheating in other servers, and I am not liable for what you do with this.
