Got a quick question and I'm wondering if I missed the answer in a tutorial somewhere.

I've had a lot of levels lately where being able to get a vertical boost as a result of chaining is necessary to get crystals in hard to reach spots. (I'm on level 67 right now.)

I know that you activate these things by getting a long chain of fruits. (I think it was 7?)

My question is, is it possible to control getting either a horizontal boost or a vertical boost as a result of the chain? Is there a trick to getting one and not the other? For me right now the horizontal ones are almost pointless and the vertical ones are critical to beating this level.

Thanks
