Can You Beat ULTRAKILL Without the London System?

Is it possible to beat Ultrakill without the London System? It has never been done before. I will be the first. Description over, go watch the video now.
Ultrakill is indeed a video game. Also, chess is. Gotham Chess is also a person. These are indeed keywords. Why are you reading the description, go watch the funny video. No, it is serious. I mispoke.
