I agree with what the first two posters have said, flawless is important on level one and somewhat so on level two. Believe it or not, your brain will eventually just automatically know the right time to click, and you will fall into a rhythm (and your score will improve a lot!). The only thing I have to add is to try to be aware of the shortest way to get to each firework. Sometimes going a direction you're not used to will get you there in only one or two clicks, vs. having to scroll through the whole list and likely missing it. The trick is to remember to do this (which I still have trouble with sometimes, and I usually get in the high 230's) -- good luck! Also, there is a fireworks video out there somewhere that WDWTigger made that shows how to get them all in some of the trickier combinations. That helped me quite a bit. I will try to find and post the link.
