I hated how awkward it was to control Mario when he went upside down, or if you HAD to jump off the freaken stage so that gravity would somehow out of nowhere save your ass and you'd be on the other side, yet other times when you fall off the stage, you die. And I didn't like how the whole game revolved around Mario spinning for an attack. And the lack of large solid ground pisses me off. Having to island hop using stupid spinning cannon things that autoguide you really annoyed me.
