Game idea

While looking around the internet at flash games I found one that someone had made which looked relatively simple to make;

a simple Brick Breaker game

You move with the directional keys, and have to avoid the falling rocks. As you get past a certain point score the rocks' speed increases, thus making it more difficult to survive. This reminded me of the classic ragdoll game where you have to avoid the spikes to survive, and achieve as high a score as you can.
