ModEngine | Super hacky and jank mod injector | Cybersecurity library

I am attempting to write a mod engine for a game.

To achieve this, i decided i would add a reference to my engine dll in Unity's Assembly-CSharp game code file, then using Mono.cecil i wrote a call to the engine into one of the functions the game calls when it loads.

I was able to add code in there that would write to file if the function was called, which worked, so either something has gone wrong with the way the engine is called (Or referenced) or unity does something to stop that behavior.
