I'm with Big H, it's very difficult, and this is for one main reason. The window of the stick that is the lead jab is way to small, and I often find myself throwing hooks or straight rights when I wanted the jab. This simply makes it difficult to box well, and ends up in a brawl.

And I can't even beat Isaac Frost on the easiest difficulty. I'm going back to playing solitaire with two suits of cards, which seems to be more my level.
