The Zazz boss fight in normal mode is in my opinion, very easy. Of course, I have played Sonic Lost World a lot more than some beginners reading this, so no offense if you are still working at that nice and powerful 'S' rank! Anyways, I challenged myself to fight and defeat Zazz without using the control stick and only jumping. I did it, and got an 'S' rank. I challenge everyone to do the same.
