So what is everyone's prefered shot/power up in this?Blue "lightening" is my goto. But if I recall, some stages I'll switch it up to better dispatch the baddies.
YouTube longplays say it's about 45 minutes. It seems longer, though, like at least an hour.
For score run secrets, you need to find all the hidden gold Z icons, destroy the snake thing from the inside after it curls into a circle, destroy the pairs of vertically moving blooming flower pot things simultaneously, get all the parts of the big balls that split into four smaller balls, and milk the 2 minute boss for points by destroying its purple shots.
... and milk the 2 minute boss for points by destroying its purple shots.aka popcorn :)
You can also use your booster thrust to damage enemies as you change speed. There's one ship that comes up from behind where this is useful (I could never get the hang of this... maybe with a 3-button pad...)
