more advice:
- hitting an already-saved piece twice makes it disappear, but hitting it once is fine, so you want to push it toward other pieces of the same colour, to make da combo chain, which gives lots of points
- if you have a really big piece that isn't saved, puh it a lot so that it carries already-saved little pieces of other colors, so that they can hit more of their brethren and make more of da combo
- try to make final pieces of a combo hit other already-dead pieces, because they give as many points as the piece that hit them, and if it's the final piece of a combo then it is a lot of points
- if your main problem is to survive, don't try to save every single piece, sometimes you will only make more pieces fall, it's okay to let some loner pieces die
