ZOMG?
i finaly know how to do it!!
you need to get all the points from the rockets,
its very hard, but dont lose any life in the first level,
than at the end you have like 100-200 rockets, 100-200k
in level 1 i had like 380k already.
do the same in level 2, than i had around 900k.
in lvl 3 i died 2 times :/, but still got kickass score =D
