Gungeon Entered!

Trust me, the first "boss," Blockner, was, as my information told me, Quite a pushover. I probably shot him five or six times, that's it. No joke. I walk into the main hall and, to my glee, the guards let me through into the Gungeon. I feel a damp, cool wind rush out of the deep chamber and into my face and down my back. As I look upon the threatening stare of the huge skull that serves as entrance to the elevator into the Gungeon, I begin to feel doubt. Is this what I should really do about this?
