This game is such a pain. The slow-mo trick works well on this game, though. Also, for the 10 power up achievements you have to get 10 of the power ups in a single play. It helps if you only collect one type during the whole play, because it takes forever to collect 10 of the same kind. Also, if you wait till the power up is halfway, or near the bottom, of the screen, there is a chances that another of the same power up will appear on the same screen - once you pick up a power up you have to wait till the effect wears off before more power ups appear again.
