Here's how it works:
* Rank is determined by your performance. The better you perform in races, the higher your rank will climb.
* Higher ranks unlock harder courses and opponents. This creates a gradual increase in difficulty as you progress.
* There is no explicit difficulty setting. You can't choose "Easy" or "Hard" at the start of the game.
So, to increase the difficulty, you'll need to:
* Improve your skills. Master the controls, tricks, and item usage.
* Complete races and unlock higher ranks. This will unlock tougher challenges.
* Try different game modes. Some modes, like "Grand Prix," will have tougher opponents and courses compared to "Free Race."
While you can't directly adjust the difficulty, the game's ranking system creates a natural progression that allows you to tackle increasingly challenging content as you become more proficient.
