Putting the shuffle phase aside, there's no combination of slices that results in a pattern that's impossible to dodge (maybe if literally all 4 bamboos were the circle aoe, but I don't think that's possible). They can all be avoided with good enough reflexes.

Which is actually pretty neat, because it's just a gold saucer game, but some patterns are close to ultimate level tuning. Ultimate predation in uwu is similar but easier due to having less randomness, and intermission 2 in a8s is another similar mechanic that's probably about on par in terms of difficulty.
