Does anybody have any tips in general for this game that I just have not picked up on yet?

I am  stuck on level 10-5 on EASY!!!
I just need to beat easy and get perfect on all the bonus levels then this game is BYE BYE for GOOD!!
I have a 2 at the end of my gamerscore, super annoying.
Any help is greatly appreciated =)
