NOPE-ing out of Ninja Launcher

Ninja Launcher is definitely the turd of the bunch in the third bundle of StreetPass Plaza games, and while manipulation potential is as low as the game's average session length, there are some gameplay tips to be had.

I'll keep this quick, you know, like a ninja:

1. You absolutely want as many people as possible.  The number of people you have is directly related to your result attack power, as well as the amount of time you have to set up your powerups.  Make use of the Plaza Update 5.0's new "Send to Line" feature if you're at a convention or in Japan or something to make sure you've got ten, and if you just can't get to ten, top off with Play Coins.
2. Do a test shot immediately.  Sometimes one or two of the Miis will start out very close to the correct position, or even already in the correct position.  This will label them so you know where you need to turn your attention to first.
3. Don't do test shots too often.  The clock still ticks down during the test shot.
4. Get everything to silver stars before concentrating on gold stars.  This will keep your scroll combo up and ensure you get the critical strike at the end, which doubles your attack power.
5. You only have to clear Novice difficulty once.  You get the Fox Hat at that point.  If you dislike the game as much as I dislike the game, you're done with it at this point and you never have to touch it again.
6. You can move a bunch of Miis at the same time, as the one you're currently moving will push any others it comes into contact with.  This comes in handy if all of their items are around the same altitude.
7. If you can momentarily divert your attention to the lower screen, you can switch to a Mii that's several Miis away much faster than by pressing L or R repeatedly.  Since you have so little time to work with, you need all the speed you can get.

Hope this helps you grind this one out so you can get your hat and never touch it ever again.
