Avoid the blocks that have a negative score; these will take points away from your value!

Also, look out for the useful power ups:

	Extra life: Gain one life.
	Slow down: Slows the speed of the game down.

But be careful; not all power ups are useful!

	Hidden Blocks: All blocks lose their colour
	Colour Swap: Changes the colours on all blocks.
	The Black Death: Lose a life.

And be careful - the game keeps getting faster and faster!
