RE: I Defeated the Hollow Knight in Steel Soul Mode

The only thing that was going on in my mind while fighting him is not to panick

This is true with almost all bosses in this game. Getting freaked out and going mad with buttons never ends well for a player and that is part of what makes this game so special. I am impressed you pulled this off, I wouldn't have been able to do that even when I was at my best in this game.
