I-Ninja All Mini Challenges 

From all challenges, Egg-Shell Skull it`s the hardest challenge in my opinion

_what a game it was, "egg shell skull" was most hardest_

Ninja ball: A solid first challenge in the game. Not so hard and not too easy. It introduces you to further challenges. Difficulty rating 4/10 Ninja Ball Ultra: Just chase the coin down the hill and you're done... Still gives us quite a challenge at the end of the track. Difficulty rating 6/10 Ninja Ball Extreme: All of your skills you've learned will be executed here. Precise movement and timing are required to complete this very challenge. Difficulty rating 9/10 Egg shell skull: You need godly reflexes to do this challenge. One hit=Death. However, Kyza's moveset is easy to predict. Difficulty rating 8/10

Thats not mini challenge but thats is mini hard challenge

DANG HOW'S IT SO CLEAR??? 4K??
