I SWEAR
Defeating this boss was the greatest thing I've actually ever felt. Even though I defeated him solo a while ago and am currently defeating the first Run and Gun on Isle 3 (this game is giving me reasons to kill myself so I slow), I still hold it as a beautiful part of my life. I don't even know why this boss was so hard for me. Trust me when I say I knew what to do. I knew where to go and how to get there. I just couldn't get past that last part if it had cost my life.
At least now I don't have to suffer anymore. I heard that the robot boss is even worse, and that's the next boss on my list. Can't wait.
