Shuriken Practice 3

You are a new recruit into the Kagenoryu, preparing for your final exam. You have chosen the shuriken as your weapon of choice and so you must prove your mastery over these throwing stars before you can join the clan.

Unlock all 8 locations by mastering level 4 on the preceding ones. Do not think this will be easy, though! Some targets give you score, some give you extra time, some deplete your time while others have a number of negative effects if you hit them.
Hit too many bad targets at the start of a new level and be thrown back a level... Hit too many bad targets and you lose automatically. Play well and you will run out of ammo pretty soon but fortunately, if you manage to hit multiple targets with a single shuriken a bonus ball (or an enemy) will appear. If you manage to hit these bonus balls you will get more ammo but be aware, they don't stick around forever and they aim to be hard to hit.
If you are unlucky enough to spawn an enemy they might just go after your bonus balls while costing you more ammo to defeat them.
Will you face this challenge? Can you master all the locations? Will your mastery be recorded for the world to see? Will you be the latest member of the Kagenoryu? Step up to the plate and let's find out..!
