The value of the chain bonuses really hurts the premise. Without them, you'd have plenty of incentive to grab all the various graphics swapping powerups, but as is, the best way to get a high score is to avoid them all like the plague, since you're eventually going to be at the point where staying with one color is netting you thousands of points per, and suddenly switching to, say, 1s and 0s is going to break your chain.
