When I first played JJ2, I had no problem playing it through, I didn't lose a single life until... Until I met Bolly. When I tried to beat Bolly I lost all my lifes. Luckilly I used Save Game option, and so after dozens of tries I finally beat him. Now I have no problem with him, but the first time he was a nightmare. I can bet Devan wasted less of my lifes in the first play.
