Use your finger to play and avoid the ninja and his attacks!
The ninja will try to move to the position of your finger. He will use various skills, such as wall jumps, smoke/flash grenades, and throwing shurikens to try and get you. You must keep your finger on the screen and react quickly to achieve the highest score.
As the game progresses, the ninja will get faster and improve his skill mechanics. Also every so often, cake will appear which can provide the ninja with a temporary powerup or you can steal it for extra score!
There is also a tutorial for new users to learn the basics of gameplay.
