Adds a new ability for you to use, holding back while on the ground will put you in a skid animation and during that animation you can perform a number of things to turn in different directions.
While in the skid you can choose to either slide, jump, trick, boost trick, or simply wait for it to end. Each variation has a different purpose and returns different amounts of speed.
Ensure you have BepInEx 5.4.21 installed, if you do not have that installed you can find it here
Navigate to the Bomb Rush Cyberfunk folder, if you have the steam version it is located at this path "Program Files\Steam\steamapps\common\BombRushCyberfunk"
Place the QuickTurn.dll into the \BepInEx\plugins folder, if you have BepInEx installed correctly this folder should already exist
Launch the game
Alternatively you can use r2modman and let that handle the entire process for you, it can be found here
I highly recommend downloading BepInEx Configuration Manager, this will allow you to edit the config while in game and can be opened once installed by pressing F1. The default settings are what I think feel the best while also being somewhat fair, but feel free to adjust them.
