Now then, I'll try to enlighten the other people here about Nanaca Crash with my non-existant wisdom.
I guess the best is to start the guy off at a relatively low angle (20�), with max speed.
The aerial boosts can be activated only when you're high enough, but still onscreen. The red one boosts you upward, and can be activated when the guy is falling. The blue one charges while you're "aerial" (high up but in the screen), and can be activated while you're rising, and it mirrors your vertical motion, so it can be tricky to actually AIM this at the girls you want to.
The characters:
I'll number them as it's on the character screen like this: 1-blue, 2-green, 3-purple, 4-yellow, and so on...
1: Hits you at 45�, so you'll be going upwards after this. The special is a basic combination attack with 4, and it activates the special break-up combo for girl 2. I think the special for girl 1 and 4 requires you only to hit the other one, or something. It happens quite often, actually.
2: She's the girl who stops you if you hit her, unless you've activated her special with girl number 1 or 4. This charged special, however, goes away once you've hit the ground.
3: She blocks 3 people you would otherwise hit. However, once you're blocked, you can activate CFF somehow. I think you need to have a special prior to hitting this girl. I think girl 6 only appears then, and has some �berspecial combo. BTW, the CFF specials I've seen are:
1) you start zapping along horizontally above all the girls for about 500m.
2) you bounce higher and higher, though this last only for 3 times
3) you get charged everytime you hit a girl, and when you'd normally stop moving, you use this charge to start again.
4)??? Don't know this one.
4: Hits you upwards, otherwise basically the same as girl 1. (combo special, break-up activation)
5: Changes your angle.
6: I've rarely seen her. I think she's some secret character or whatever. I think you have to hit girl 3 to get her.
7: She hits you horizontally, also activates the break-up special and her own special. This means if you hit her consecutively, you can get major speed boosts. Her special boost you quite a bit, I recommend using this if possible.
8: Slows you down.
9: Umm... you're whacking this guy... poor thing.
Actually, I'm beggining to think there's a need for a Nanaca Crash thread.
