Are there any cheats for level 29 of bubble struggle 2

YES!!!! Don't bother shooting anything (unless you have to).
Go past the red ones and up the ladder.
Shoot the brown block thing, get the red 'force field' (you know what I mean)
Then shoot the yellow floating bubble.
Run past all the green bubbles with your red force field (it should last long enough)
Then shoot the little brown box in the top right hand corner.
There will be a star!
Get the star - all the bubbles will pop!
Now you can go on to level 30! (don't worry about 30 - it's not too hard!)
