I agree with the last guy. Most of the new levels.
....rely on luck rather then skill which is ultra annoying. EG: Lev 8 Made a perfect shot 28 times in a row but the balloons would not all pop. Also there are collision detection problems. Often i saw a spiked ball go througha bloon doing nothing. And why does try again flash when the spiked balls are still doing their thing. Too frustrating which is a shame. This could have been front page if executed better.
