I don't know. The difficulty seemed to rely more on a terrible camera control and poor 3D platforming than anything else. I just don't remember having a whole lot of fun while playing it. As a matter of fact, the most fun I had with that game was playing Jetpac on the arcade thing.
It certainly wasn't bad, and I don't have much to back up my feelings on this, but my memories of that game are full of me being frustrated and having very little fun. The final boss comes to mind. I mean, having a boxing match with King K. Rool where the Kremlins help him cheat was hilarious and amusing, but the fight itself was so tedious and frustrating and gimmicky. That was kind of the whole game for me.
