Massive Bug
This is an awesome game, and i've played it multiple times, because the concept is awesome. My only gripe is I wish there were more levels. Also, for some odd reason, I had a bug where Bowser jumped, and the attack where he shoots out a amssive amount of flames kind of mergged together, so as he was jumping, he was tossing out about 30 fireballs all at once which were impossible to dodge. I dunno how that bug could've happened and it's the only time to ahve happened, but wow lol. Might want to be an attack you'll want to consider if you add higher difficulty levels.
