Sadly my headset is broken. No more updates until i will get a new one.
This is a library for a future plugins/mods.
Be sure that you are already installed BepInEx (using MonkeModManager for example). You need x64 version. Take it there.
If your BepInEx copy installed then copy-paste BananaHook.dll to your Gorilla Tag/BepInEx/plugins folder somewhere (Gorilla Tag/BepInEx/BananaHook/BananaHook.dll for example).
