How about reducing the bricks again significantly, and instead measuring the time players take to complete the level? They could then post their high score to Facebook or something.

Great idea. That would make the gameplay much more interesting.

I felt the level was too easy, after a while it just got repetitive.

If you want to make it harder, then you should consider making it faster and the reflection angles a bit more random.

Or as Udo suggests, play for time.

I was expecting an easter egg on completion. Instead, i got 200 alert messages.
