...Wha?
I grew up in the Super Nintendo/N64 era where A is usually Jump and B is attack. In the NES era B is usually Jump. My brother said I should try the default controls since I mentioned having a bit of trouble with Kirby's Adventure and it actually worked for me.
I also suck at all types of platformers, though Kirby is mostly an exception however Kirby's Adventure is slightly harder than the others since you're so limited with what you can do with your powers unlike other games, not to mention they give you redundant powers because of those limits. I'm also ashamed to admit that I've never beat the original Dream Land since not only did they not have powers but a boss rush which I'm terrible at. I beat Revenge of the King and Meta Knight Ultra in Super Star Ultra but I had to have my brother beat the Arena for me because like I said I'm terrible at boss rushes.
That's why I play a lot of JRPGs, I just suck at vidya gaems.
