I don't think I like this idea. Being able to slow down the bricks sounds
like cheating the game to me.

I could, but not fast enough. Loading a value from zeropage takes three cycles
and storing the value to a register takes another three cycles. For each
cycle there are three pixels drawn. Each collumn is only four pixels wide,
so it won't work. 

It could be done using interlacing and the five sprites trick, but it would
result inf a flickering picture much more need for fast RAM to store the
colourvalues for each collumn and much more complicated checking routines.
So I don't think it would be worth the effort.
