This was made during a game jam and I want to leave it how it is for preservation purposes. I also don't want to deal with the rushed spaghetti code and all the bugs. Even if i was willing to go through the mess of code, there isn't enough buttons on an NES controller.
I do have plans to completely rebuild this project from the ground-up. But I currently got some other stuff to make so it may take a bit of time until then.
