[RQ] Scoring and tips for Space Invaders Extreme (PSP)

[Blade]

Alright, well...when I first picked up this game, I thought I could play it since I'm halfway decent with other shmups like Ikaruga and such.

But this sort of game has me slightly irked now with its special enemies and patterns and all that stuff that I'm not used to because I never really practiced on the original.

Bonus Rounds also irk me as I either pull it off or it's incredulously hard to time my shots.

I could use some tips from people who've played this or at least tips on dealing with patterns and avoiding attacks.
