Tumblebugs 2--last level

I've been playing for a while now, and have arrived at the Level 8 of 12 in the expert area, and I just can't seem to beat it for anything. (I barely beat this level in the beginner category, but expert has me stumped.) Are there any tips or tricks, or anything I should know about how to get it going for all four lines at once? Thanks!

I can't seem to get out of Level 9 in Tumblebugs 2. Anybody have any ideas. I can get up through level 4 and then no further.....usually when I arrive at 4, I have only one life to live!!
